PDF to EPUB Converter

Turn PDF files into EPUB in a couple of clicks. PDF is a fixed-layout document format that looks identical everywhere; EPUB is the open reflowable e-book standard. The result is a best-effort reconstruction; check it before relying on it.

How to use it

1
Add your PDF documents
Drag them onto the drop area, choose them from your device, or paste them from your clipboard. You can queue several at once. Nothing is sent anywhere — the file stays on this device.
2
Adjust the settings if you want to
There is nothing to configure, and the result is a reconstruction rather than a copy. How close it lands depends on how the original PDF was built, so read it through before relying on it.
3
Convert and download
Press Convert. Everything happens on your own device — nothing is uploaded. Download files one by one, or grab them all as a ZIP.

Privacy, in plain words

Is it safe? Your PDF file is not uploaded anywhere

What “uploaded” normally means. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website. That copy is what the word “upload” means, and it is the part nobody explains.

What happens instead. This site does not do it. There is no server here that receives files, so your PDF file is read, converted and handed back by the browser you are using right now. It never travels — so there is no copy to store, read, leak or hand over.

Check it yourself in ten seconds

Turn off your Wi-Fi after this page has loaded, then convert a file anyway. It still works, because everything needed is already on your device.

The longer explanation of how this works, and the full detail of what is and is not stored on the privacy page.

Why this matters more than it sounds

PDF is the format people use for exactly the documents they would not hand to a stranger. It matters more than it sounds, because of what PDFs usually are:

Tax returns

income, dependants, tax file or social security numbers

Passport and visa scans

the single most useful document for identity theft

Medical letters and results

a diagnosis is not something to leave on a server

Payslips

salary, employer, and usually your home address

A file that is never sent cannot be kept, leaked, subpoenaed or used to train anything. That is a property of how this works, not a promise about how carefully it is run.

PDF and EPUB explained

PDF describes a page as a fixed arrangement of text, vector graphics and images. Unlike a word processor document, it is designed so the page looks identical everywhere — which is exactly why it is awkward to edit.

EPUB is essentially a website in a box — a ZIP of XHTML and CSS. Because the content is reflowable, the reader chooses the font size and the text re-wraps, rather than being locked to a page.

Where PDF files come from: Contracts, invoices, reports, forms, academic papers and scanned documents.
Where EPUB is used: E-book stores, library lending and self-publishing.

PDF vs EPUB

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

PDF compared with EPUB
Property	Source	Target
Compression	Lossy or lossless	Lossless
Introduced	1993	2007
Browser support	Universal.	Everything except Kindle's older formats.

PDF is stronger at: Looks identical on every device, in every viewer, when printed. Supports digital signatures, forms and embedded fonts. Universally readable without special software.
EPUB is stronger at: Text reflows to any screen size and font preference. Open standard. Supported by Apple Books, Kobo, Google Play Books and most readers.

Why convert PDF to EPUB?

People make this switch when they run into the limits of PDF: the document still needs collaborative editing. EPUB is the better fit when distributing text-based books meant to be read on a device.

PDF limitations that prompt the switch: Genuinely hard to edit — it stores positioned glyphs, not paragraphs. Scanned PDFs contain no text at all until OCR is run. Can be large when it contains high-resolution images.
What you give up: Kindle needs conversion or a different format. Fixed-layout content such as comics works poorly.

What is preserved when converting PDF to EPUB?

This is a reconstruction, not a copy. FileTools360 interprets the PDF file and rebuilds it as EPUB, which works well for straightforward content and progressively less well as the original gets more complex. Check the output before relying on it — the caveat beside this converter says what specifically does not carry across.

Measured, not estimated

What converting PDF to EPUB actually costs

The EPUB came out 19% smaller than the file that went in.

Good to know

PDF to EPUB Converter — questions

How do I convert PDF to EPUB?

Drop your PDF file onto the area above, then press Convert. The EPUB file saves straight to your device. You do not need an account, and there is no watermark.

Is it safe to convert PDF files here — are they uploaded to a server?

No, nothing is uploaded. On most online converters, pressing the button copies your file across the internet onto a computer owned by that website; it is converted there and sent back. That copy is what "upload" means, and it is the part that puts your file out of your control. This site does not do it. Your PDF file is read and converted by the browser you are using right now and never leaves this device, so there is no copy for anyone to store, read or hand over. You can prove it: turn off your Wi-Fi after this page loads and the conversion still works.

Can I convert confidential PDF files, like bank statements or contracts?

Yes, and that is the case this site was built for. Because the file never leaves your device, a confidential document is no more exposed than it is sitting in your own folder — there is no transfer, no copy on someone else's hardware, no retention period to read about and no staff with access. Nothing is logged about the file either: not its name, not its size, not its contents. The one thing worth saying plainly is that this protects the file in transit and at rest on our side, not from anything already on your own computer.

What should I know before converting PDF to EPUB?

The text layer is extracted and re-flowed into chapters. Page-based layout, columns and image placement are not reproduced — this is for reading, not for archiving.

What is preserved when converting to EPUB?

The result is a reconstruction rather than a perfect copy. It is genuinely useful for reading and reuse, but review it before relying on it for anything important.

How large a file can I convert?

Up to 150 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android. Pick the file through your phone's file picker — Files on iOS, or Downloads on Android — including files stored in iCloud or Google Drive.
