Turn a PDF into a book your e-reader actually enjoys.
Reading a PDF on an e-reader is miserable. Fixed pages, tiny type, endless pinching and panning. This rebuilds the text into a proper EPUB with real chapters, a working table of contents and type that resizes. All of it inside this tab.
Read in this tab. Never uploaded. Here's why that's true.
This looks like a scan.
We found page images but no selectable text. Convert it and you'll get a book with nothing in it. Run it through OCR software first. We don't do OCR here.
These become the title and author in your library, which is what your device sorts by. Worth thirty seconds.
Working…
This runs on your machine, so the speed is down to your machine. Keep the tab open.
Your EPUB is ready
Getting it onto your e-reader
- Kindle: open Send to Kindle and drop the EPUB in, or email it to your @kindle.com address from an approved sender.
- Kobo, Nook, PocketBook: plug the device in over USB and copy the file across. EPUB is their native format, so there is no conversion step.
Amazon converts the EPUB themselves once it arrives. They stopped accepting MOBI in 2022, which is why nobody should be making you one.

What it actually does
A PDF only records where each character sits on the page. Paragraphs, chapters, reading order: none of that is in the file. It all has to be worked out. Here's how.
- 01
Pick a PDF
Drop the file on the page. It goes straight from your disk into the browser tab. No upload, no queue, no waiting on a server.
- 02
We rebuild the text
A PDF stores glyph positions, not sentences. So the converter reads every page and works backwards: lines become paragraphs, words broken across a line end get stitched back together, and repeated headers, footers and page numbers get thrown out.
- 03
Chapters and pictures go back in
If the PDF has bookmarks, those become your chapters. If it doesn't, we guess from the headings. Figures get lifted out and dropped back where they sat on the page.
- 04
Download and send
Out comes a proper EPUB with a cover and a table of contents. Kobo, Nook and PocketBook read it as-is. For a Kindle, use Send to Kindle, email, or a USB cable.
Converting for a particular device
Same converter, but the transfer step and the gotchas differ quite a bit by device.
Why the privacy bit holds up
There is nowhere to upload to
The site is static files on a CDN. No API, no server of ours doing anything. The converter is code your browser downloads and runs. We couldn't collect your file if we wanted to.
Nothing gets kept
No accounts, no history, no storage bucket, no database. Your EPUB lives in a browser tab until you download it. Then it stops existing.
Works with the wifi off
Load the page once, then disconnect and convert anyway. Easiest proof going that nothing is being sent.
Common questions
Is my PDF uploaded anywhere?
No. The converter is JavaScript running in your browser. It reads the file off your own disk and never sends it anywhere. Don't take our word for it: open devtools, watch the Network tab, and convert something. Nothing goes out.
Why EPUB and not MOBI or AZW3?
Amazon stopped taking MOBI for new documents back in 2022, and Send to Kindle now handles EPUB directly, converting it on their end. So EPUB is what you want. It's also the one format a browser can build properly.
Will it work on a scanned book?
No, and it can't. A scan is just photographs of pages, so there's no text in the file to pull out. You'd need OCR software first. We check for this before you convert and tell you, rather than handing you 300 blank pages.
How good is the result?
Good on ordinary prose. Novels, reports, papers and manuals come out reflowable with chapters that work. It struggles with heavy layout: magazines, wide tables, sheet music, equation-dense maths. A reflowable ebook has no fixed page, so anything that depends on where things sit is going to suffer.
Is there a file size limit?
Around 300 MB in practice. The whole document sits in your browser tab while it converts, so a big one can run the tab out of memory. Most books are a few megabytes, so this rarely comes up.
Do you keep the converted EPUB?
We've got nowhere to keep it. The file is assembled in memory and handed to your browser as a download. Close the tab and it's gone.
Does it work offline?
Yes, once the page has loaded. Pull the plug and convert away. It never needed the network in the first place.
Can I convert a book I do not own?
That's between you and whoever holds the copyright. We're a format converter and we never see your file, but converting something you have no right to copy is still infringement. Stick to what you're entitled to.
