PDF to EPUB: how it works
To convert a PDF to EPUB, open the PDF to EPUB tool and add your file — PDFER extracts the text, reflows it into a standard EPUB 3 e-book (headings and paragraphs preserved), and downloads it, all in your browser with nothing uploaded.
How to use PDF to EPUB
- Open the PDF to EPUB tool and add your PDF.
- Click Convert to EPUB.
- Download the .epub and open it in any e-reader.
In your browser vs. uploading to a server
Best for reading a text-based PDF comfortably on a Kindle, Kobo, or phone, where reflowable text beats a fixed PDF page. It converts the document's real text — a scanned PDF needs OCR first to gain a text layer.
Frequently asked questions
Will the EPUB reflow to my screen size?
- Yes. Unlike a PDF's fixed pages, the EPUB is reflowable text, so e-readers can resize and repaginate it to fit any screen.
Does it keep images and exact layout?
- It focuses on text and heading structure for clean reading; complex fixed layouts and images are simplified. For a pixel-faithful copy, keep the PDF.
Are my files uploaded to a server?
- No. PDFER runs entirely in your browser using WebAssembly and JavaScript. Your files are read into memory on your device, processed locally, and never sent to PDFER or any third party. Closing the tab or leaving the tool erases them from memory.
Is it free, and is there a file-size limit?
- Yes, it is free with no account, no watermarks, and no daily caps. Because processing happens on your own device, the only practical size limit is your device's available memory rather than a server upload quota.
