Flipbooks AI vs Sejda: Do You Need to Fix the PDF or Publish It?

The Short Answer

Choose Flipbooks AI if the PDF is finished and what is missing is somewhere to put it: a page turning flipbook on a link anyone can open in a browser, with no page cap, no hourly quota, your own logo and brand colours on any paid plan from $59 a year, and a document that stays live until you delete it. Nothing here changes what is inside the file, and that is deliberate.

Choose Sejda if the file itself is the problem. Sejda edits text and images inside an existing PDF, merges, splits, compresses, converts to and from Office formats, runs OCR, fills and signs, and puts a real password on the file, most of it with no account at all. Sejda Desktop goes further and processes the file on your own computer instead of uploading it, which is a privacy position Flipbooks AI cannot match at any price. For most people these two are not rivals. You fix the PDF in Sejda, then publish it here.

Flipbooks AI vs Sejda at a Glance

Flipbooks AI wins 8 of these 11 rows, ties 3 and loses none. They are rows we picked, so read them that way. The sections below say plainly where Sejda is the better buy.

Pricing Compared

Sejda's plan page, read in August 2026, served us euro figures: a Web Week Pass at 5.50 euros per user for seven days as a one time payment, Web Monthly at 8.50 euros per user a month, and Desktop plus Web Annual at 71 euros per user a year, which the page describes as saving 30 percent against monthly. A volume discount of 20 percent starts at ten or more users and their page says it scales further for large teams. The page localises, so the amounts you are shown may be a different number in a different currency rather than a converted symbol. Take your own view as the truth and treat the euro figures here as what we were served.

What a Sejda subscription buys is throughput rather than features you do not already see. Their own comparison lists browser based access to all PDF tools, unlimited documents with no page or hourly limits, OCR up to 100 pages, processing multiple files at once, more processing time per task at up to 21 minutes, large file uploads up to 500MB per file, and email support. In other words the free tools are the paid tools, with the ceilings taken off. That is a clean and unusually honest way to sell software, and it makes the free tier a genuine trial of the real product rather than a demo.

Flipbooks AI sells three plans in USD on one page, the same price wherever you check from, checked in August 2026. Starter is $59 a year and is annual only. Plus is $14 a month or $108 a year. Ultra is $29 a month or $228 a year. Every paid tier removes the small corner mark or swaps your own logo into its place and unlocks brand colours, Plus adds the embed code with an allowed domain list, and Ultra adds background music and a separate password for each reader. Comparing the two ladders directly is not much use. Sejda is priced by how much file processing you do, and we are priced by how a finished document looks and behaves for the people reading it.

What Each Free Plan Really Gives You

Sejda's free tier is the most explicit we have come across, and that deserves credit before anything else. The limits are printed in the product rather than buried: three tasks an hour, 50 MB per file, 5 MB per image file, one file per task, 20 pages per conversion, 20 links per task and 10 pages per OCR task. The editor's own messages quote a free limit of 50 pages, while the same page also describes a free service for documents up to 200 pages or 50 MB with three tasks an hour, so the page ceiling is tool specific rather than one number. Sejda Desktop has its own free shape: three tasks a day, documents up to 50MB and 200 pages, compress up to 100MB, OCR up to 10 pages, images up to 5MB, and combine up to 30 files and 50 pages.

The part that matters most is what the free tier does not ask for. There is no signup, so you can land on a Sejda tool, fix a file and leave without creating an account, and nothing is stored waiting for you to come back. For a person who needs to rotate four pages of a scanned contract once a quarter, that is close to perfect, and no subscription anywhere is going to beat it. The hourly quota only becomes a wall when you are doing a batch, which is exactly when the paid plan is worth its money.

The Flipbooks AI free plan is a hosting allowance rather than a task allowance, so it counts different things. Three flipbooks stay live at once with 1 GB of storage, there is no page cap, no hourly quota and no ads beside the reader, readers never need an account, and a single shared password is allowed while you are still free. The limits, up front: free flipbooks use the magazine page turn effect only and carry a small corner mark, and the embed code starts on Plus at $14 a month or $108 a year. The three flipbook allowance rolls, so deleting one frees the slot straight away and a free account can publish far more than three documents over a year.

Branding and Watermarks

Ours first, because a comparison that hid its own mark would not be worth reading. A free Flipbooks AI flipbook carries a small mark in the corner of the viewer. Any paid plan removes it, starting with Starter at $59 a year, and you can either hide it entirely or put your own logo in its place, with brand colours for the reader controls unlocked at the same step. That is the whole branding ladder here: one rung, one price, and every tier above it carries the same thing, so there is nothing further to be upsold into.

On Sejda's side there is nothing equivalent to report, and the reason is structural rather than generous. Sejda hands the file back to you. There is no viewer of theirs wrapped around your pages, so there is no corner logo to remove and no plan that sells you the removal. What we will not do is tell you whether a file that comes out of a Sejda tool carries a Sejda mark anywhere on the page, because their public pages do not state it either way and we did not verify a live output file. Treat that as unchecked rather than as a promise in either direction. Sejda does sell a watermark tool, but that is for stamping your own mark onto a document rather than theirs.

The layer each product controls is the cleanest way to see the difference. Sejda changes what is printed on the pages: the text, the images, a watermark you asked for, a header, page numbers. Flipbooks AI changes the frame around the pages: the corner mark, the reader colours, your logo where ours was. Neither one reaches into the other's layer, which is why the two sit together comfortably in the same workflow and why price comparing them is close to meaningless.

Privacy and Who Can Find Your Flipbook

This is the section where Sejda is plainly stronger, and pretending otherwise would be dishonest. Their privacy policy states that all user uploaded files as well as the processed output files will be permanently deleted after upload or processing respectively, and that when you generate a public sharing link, the access link and the shared files will be permanently deleted automatically, seven days after being shared. Sejda Desktop goes further still: their own page says that with Sejda Desktop files are processed on your computer, not uploaded to our servers. A file that never leaves your machine is the strongest answer available to the question, and we do not have one.

A Flipbooks AI flipbook works the other way, because hosting is the product. It is reachable by its link and nowhere else, it is never listed in a public directory, there is no public profile page, and we never submit it to a search engine, including on the free plan. A single shared password works while you are free, and a separate password for each reader comes with Ultra at $29 a month or $228 a year. One limit stated about our own product: a Flipbooks AI password gates the reader interface rather than the file behind it, so a document that genuinely must not leak needs a system with real access control instead.

That last point is worth putting next to something Sejda does that we cannot. Their protect tool puts a password on the PDF itself, and that password travels with the file wherever it goes, including into an email attachment or a shared drive. It is a different kind of protection from ours and a stronger one for a document that is being sent rather than published. If your board pack has to be locked, lock the file in Sejda first. Then decide separately whether it should be online at all, because a link, any link, is a public URL the moment somebody pastes it somewhere public.

Embedding and Sharing

Sharing exists on Sejda, and it is more useful than a file processor usually needs to be, but it is temporary by design. After a task you can generate a public sharing link, and their privacy policy is explicit that the link and the shared files are deleted automatically seven days after being shared. There is one exception worth knowing about: their fillable forms tool has a publish step whose link does not expire and can be shared on a website or in an email, and because Sejda says they do not offer document storage, that published form is saved in your own Google Drive rather than on their servers. So a form can live indefinitely, while a shared processed file has a week.

No embed code is documented anywhere on Sejda's pages, and we would not expect one. Embedding means the vendor hosts the document and hands you an iframe, which is the opposite of a tool built to delete your file the moment it has finished with it. If you need a PDF sitting inside a page on your own website, Sejda is not the product that does it, and no plan of theirs changes that. On Flipbooks AI the embed code starts on Plus at $14 a month or $108 a year, and it comes with an allowed domain list so you control which sites may frame your flipbook.

Plain link sharing is where the two are closest and still different in kind. Both give you a URL a reader opens in a browser with no account. Ours opens a page turning flipbook you have branded, it stays live until you delete it, and readers on a phone get the same document as readers on a desktop. Theirs opens a file for a week so somebody can download it. For sending a corrected invoice to one person on a Tuesday, a week is plenty and simpler. For a catalogue whose link is printed on a leaflet, a week is a problem.

Ease of Use and What Each Tool Is For

Sejda is one of the better designed tools of its kind, and the design decision that matters most is the absence of a front door. You arrive at the tool you need, you use it, you leave. There is no onboarding, no project, no library, no dashboard to keep tidy, and no account unless you want one. The tool list is wide: editing text and images inside a PDF, merge, split, compress, convert to and from Word, Excel and PowerPoint, OCR, fill and sign, protect and unlock, crop, rotate, page numbers, watermarks and more. If your problem is a broken or badly built file, this is the shape of tool that fixes it, and the desktop version fixes it without the file leaving your computer.

Flipbooks AI is narrower on purpose, and it is easier to say what it is not. There is no template gallery, no in tool page editor, no custom domains, no team seats, no API, no reader analytics and no lead capture forms. The design work already happened wherever you made the PDF. You upload the finished file, choose a page turn effect, set a password or your colours if you are paying, and share the link. We also cannot do a single thing Sejda does: we will not merge two files for you, we will not compress a heavy one, and we will not fix a typo on page nine.

Which is why the honest recommendation in most cases is both, in order. Assemble and repair the document in Sejda, or in whatever made it, until the PDF is genuinely finished. Then decide whether it needs to be a page on the internet that people read, or just a file you send. If it is a file you send, you do not need us, and we would rather say that than sell you a subscription you will forget about. If it needs to be read by strangers on a link, with a page turn and your brand around it, that is the job this product does.

Who Should Choose Which

Choose Flipbooks AI if

• Your PDF is finished and it needs to be online, branded and readable in a couple of minutes
• You want a link that stays live until you delete it rather than one that expires after a week
• You want your own logo and brand colours on the cheapest paid plan, $59 a year
• You need an embed code so the document sits inside a page on your own website

Choose Sejda if

• The file itself needs changing: text edits, merging, splitting, compressing, converting or OCR
• You want to work with no account at all and nothing kept on a server afterwards
• You need the file processed on your own computer, which Sejda Desktop does and we cannot
• You need a real password on the PDF itself, one that travels with the file when you send it

How to Switch from Sejda to Flipbooks AI

Calling this a switch is not quite right, because the two tools do different jobs and most people keep using both. What follows is how to get a document out of a Sejda workflow and onto a link that lasts.

1. Finish the file in Sejda first. Do the merging, the page order, the compression and the text fixes while the document is still a file, because none of that is possible once it is a flipbook. Export the final PDF and keep that export as your master copy, since Sejda deletes processed files after the task and your own copy is the archive.
2. Check nothing was clipped by a free limit. Free conversions stop at 20 pages, OCR at 10 pages and uploads at 50 MB per file, and a document that hit one of those quietly is a document that is missing something. Open the final PDF at full size, check the last page is really the last page, and confirm the text is still selectable if you ran OCR.
3. Decide whether it should be published at all. If the document is going to one person and must stay locked, put a password on the file in Sejda and send it, and stop here. Publishing is the right answer for things strangers are meant to read on a link, such as a catalogue, a brochure, a report or a portfolio.
4. Upload the PDF to Flipbooks AI and set it up. Drop the file on the create page, pick a page turn effect, add a password if the document is private, and set your own logo and brand colours if you are on a paid plan. Preview it before publishing, and remember the free plan keeps three flipbooks live at a time with the magazine effect.
5. Repoint anything that used a temporary link. A Sejda sharing link is gone seven days after it was shared, so any email, message or document that pointed at one is already broken or about to be. Replace those with the flipbook URL, and if you are embedding it on your own site, set the allowed domain list on Plus so only your pages can frame it.

Frequently Asked Questions

Is Sejda free, and what does the free tier include?

Yes, and it is unusually clear about what free means. On the web you get three tasks an hour, 50 MB per file, 5 MB per image file, one file per task, 20 pages per conversion, 20 links per task and 10 pages per OCR task, with a page ceiling that varies by tool between 50 and 200 pages, checked in August 2026. No signup is required. Sejda Desktop has its own free shape of three tasks a day with documents up to 50MB and 200 pages. Our free plan counts something different: three flipbooks live at once on 1 GB, with no page cap and no hourly quota.

Does Sejda make flipbooks?

No, and nothing on their pages claims it does. Sejda is a PDF toolbox, so it changes what is inside a file and hands the file back to you. There is no page turning reader, no hosted viewer for an audience, no branding controls around the pages and no embed code. If what you want is a document that opens in a browser and turns like a magazine, that is a different category of product, and this is the honest reason the two tools tend to be used together rather than instead of one another.

How much does Sejda cost?

Their plan page served us euro figures in August 2026: a Web Week Pass at 5.50 euros per user for seven days as a one time payment, Web Monthly at 8.50 euros per user a month, and Desktop plus Web Annual at 71 euros per user a year, described as saving 30 percent against monthly, with a 20 percent volume discount from ten users. The page localises, so your currency and the actual number may both differ. Check your own view rather than trusting a figure quoted anywhere else, including here.

What exactly do you get by paying Sejda?

Ceilings, mostly, and that is meant as a compliment. Their own comparison lists browser based access to all PDF tools, unlimited documents with no page or hourly limits, OCR up to 100 pages, processing multiple files at once, more processing time per task at up to 21 minutes, large file uploads up to 500MB per file, and email support. The free tools and the paid tools are the same tools. If you only fix a file occasionally you may never need to pay at all, and a vendor whose free tier is a real version of the product is worth trusting a little more.

How long does Sejda keep my files?

Not long, deliberately. Their privacy policy says all user uploaded files as well as the processed output files will be permanently deleted after upload or processing respectively, and that when you generate a public sharing link, the access link and the shared files will be permanently deleted automatically seven days after being shared. Sejda Desktop does not upload at all, since files are processed on your computer. Flipbooks AI is the opposite by design: hosting is the product, and a flipbook stays live until you delete it.

Can I embed a Sejda document on my own website?

No, and no plan of theirs adds it. Embedding requires the vendor to host your document and give you an iframe, which is at odds with a service built to delete your file as soon as it has processed it. Their one long lived link is the publish step in the fillable forms tool, whose link does not expire and which stores the document in your own Google Drive because Sejda does not offer document storage. On Flipbooks AI the embed code and its allowed domain list start on Plus at $14 a month or $108 a year.

Which tool has better password protection?

Sejda, for a document you are sending. Their protect tool puts a password on the PDF file itself, so the protection travels with the file into an email or a shared drive. A Flipbooks AI password gates the reader interface rather than the file behind it, which is worth knowing before you rely on it, so anything that genuinely must not leak belongs in a system with real access control. What we add is convenience at the reader end: one shared password on the free plan, and a separate password for each reader on Ultra at $228 a year.

Is there a page limit or a file size limit?

On Sejda, yes, and they are the main reason people upgrade. Free use caps files at 50 MB, images at 5 MB, conversions at 20 pages and OCR at 10 pages, with a general document ceiling quoted between 50 and 200 pages depending on the tool, while paid use lifts the page and hourly limits and takes uploads to 500MB. Flipbooks AI sets no page cap at all, so a 300 page catalogue goes up whole, and the free plan's real ceiling is the 1 GB of storage rather than the page count.

Do I need an account with either tool?

For Sejda, no, and that is one of its best features. You can open a tool, process a file and leave without ever creating an account, which is why it works so well as an occasional utility. Flipbooks AI does need an account, because the product is hosting: something has to own the flipbook, hold its settings and let you delete it later. Readers, on the other hand, never need an account with us and never see a sign up prompt, on any plan including free.

Is Sejda a good tool?

Yes, and a comparison that pretended otherwise would not be worth reading. It is one of the clearest PDF toolboxes available, it works with no signup, its free limits are printed in the product instead of hidden, its paid plan removes ceilings rather than unlocking features you were shown and denied, and Sejda Desktop processes files on your own computer, which is a stronger privacy answer than anything we offer. The split is simply that Sejda changes what is inside a document and Flipbooks AI publishes the finished one, so plenty of people should use both and some should use only Sejda.
