How to convert a PDF to EPUB (and make it actually readable)
A PDF is a picture of a printed page. On a 6-inch e-reader or a phone, that means tiny text, endless zooming and sideways scrolling. An EPUB fixes that: the text reflows to fit your screen and your font size, with real chapters you can jump between.
The catch is that most converters turn a PDF into a messy EPUB. Page numbers land in the middle of sentences, words break apart, and chapters vanish. This guide shows how to get a clean one.

What Epubby fixes
These are the things that usually go wrong when a PDF becomes an EPUB, and what Epubby does about each one.
| Problem in the PDF | What Epubby does |
|---|---|
| No chapters, just one long scroll | Builds chapters from the PDF's outline, its printed contents page, or the chapter headings in the text |
| Broken letters like “fi ve” or “Th e” | Repairs joined letters (ligatures) so words read normally |
| Words split across lines (“conver- sion”) | Mends hyphenated line ends and joins paragraphs that run across pages |
| Page numbers and running heads in the text | Drops them, so sentences aren't interrupted |
| A title like “Microsoft Word - final v2” and no author | Finds the real title and author from the book or the file name |
| No cover | Uses the first page as the cover, and you can upload your own |
| Blank pages | Removes them |
| Pictures and diagrams | Keeps illustration pages as images |
Tips and FAQs
Which PDFs convert best?
Text-based PDFs: ebooks, articles and documents saved from Word or Google Docs. If you can select and copy the text in your PDF viewer, it will convert well.
What about scanned PDFs?
A scan is a photo of each page. If the scan has a hidden text layer (OCR), Epubby uses it and clears out the junk characters scans tend to have. Without that text layer, pages come through as pictures, so run the scan through an OCR tool first.
What about textbooks with columns, tables and maths?
Simple layouts convert cleanly. Dense two-column pages, big tables and equations are hard for any converter, so check those chapters after converting.
Can I fix the chapter names?
Yes. You can rename chapters, change the title and author, and swap the cover before saving.
Is there a size limit?
Files up to 25 MB.
Can I convert EPUBs too?
Yes. Drop in a messy EPUB and Epubby tidies it the same way: cover, title, author and chapters.
Please only convert files you have the right to use.
Next: get it onto your e-reader
