E-readers and phones are perfect for reading — just not for PDFs. A PDF page is built for A4 or Letter paper: on a six-inch screen the letters become tiny, and zooming in means endless scrolling left and right.
The fix is converting PDF to EPUB, the e-book format with reflowable text that adapts to any screen. The short answer: upload your file to our online PDF to EPUB converter, wait for processing and download the book. Load it onto Kobo or PocketBook, open it in Apple Books or Google Play Books, or send it to Kindle. Free, no registration, no watermarks.
Quick answer: how to convert PDF to EPUB
- Open the PDF to EPUB converter on my-pdf.ru.
- Upload one PDF up to 100 MB.
- Click Convert to EPUB and wait for processing.
- Download the book and move it to your reader or app.
What EPUB Is and How It Differs from PDF
EPUB (Electronic Publication) is an open e-book standard maintained by the W3C. Inside, an EPUB is a ZIP archive with HTML pages, CSS styles, images and a table of contents — essentially a small website that the reading app renders to fit the screen, using the font, size and spacing you choose.
PDF is the opposite: a fixed-layout format where each page looks exactly as designed. Great for print and carefully designed magazines, uncomfortable on small screens.
| Feature | EPUB | |
|---|---|---|
| Layout | Fixed, paper-like pages | Reflowable, adapts to the screen |
| Font size | Only by zooming the page | Set in the reading app |
| Reading on a 6-inch screen | Awkward | Comfortable |
| Complex design, diagrams, formulas | Exact | Simplified |
| Bookmarks, notes, dictionary | Depends on the app | Supported by most readers |
Which PDFs convert well
- Excellent: novels, articles, stories and single-column manuals.
- Good, with caveats: textbooks and non-fiction with a few images and simple tables.
- Poor: magazines, comics, catalogues, two-column papers, documents full of formulas and diagrams — read these as PDF on a tablet.
- Not suitable: scans without a text layer, which stay as page images that do not reflow.
What Happens to PDF Elements in EPUB
| PDF element | Result in EPUB |
|---|---|
| Single-column body text | Reflowable text that fits the screen |
| Bold and italics | Usually kept |
| Illustrations and photos | Kept as images inside the book |
| Simple tables | Kept, but may feel cramped on a narrow screen |
| Multi-column layout | Simplified; reading order may break |
| Headers and page numbers | May end up inside the text |
| Formulas and complex diagrams | Simplified or less accurate |
| Scanned pages | Stay as images without reflowable text |
The closer a PDF is to an ordinary book, the better the result. Note also that EPUB has no fixed page 57: page numbers depend on screen and font size, so in-text references like see page 57 lose meaning, and you navigate by the table of contents and reading progress instead.

How to Load EPUB onto Your Device
Kobo, PocketBook and other e-readers
Connect the reader by USB, copy the EPUB to its Books folder (or any folder) and eject. Many devices also support cloud sync or sending books by e-mail.
iPhone and iPad
Open the file in the Files app and tap Share, then Books. It appears in Apple Books with progress synced across devices.
Android
Use Google Play Books (upload in the library), ReadEra, PocketBook Reader or Moon+ Reader.
Kindle
Kindle did not read EPUB natively for years, but Amazon now accepts EPUB through Send to Kindle — via the app, the website or your device's e-mail address. Amazon converts the book and delivers it automatically.
Alternative Ways to Convert PDF to EPUB
calibre
calibre is a free e-book manager and the best-known format converter. It offers fine control: removing headers and footers with regular expressions, heuristic processing of hyphenation, table of contents settings. It is powerful and local, but you need to install it, the interface is busy, and good PDF results often take experimentation. For a one-off conversion, the online service is simpler.
Going through Word
For a book you will reread, convert PDF to Word, clean the text by hand (remove page numbers, set headings), then build the EPUB in calibre. Slow but thorough.
Buying the official EPUB
If the book is published commercially, check e-book stores — a publisher's EPUB is almost always better than any automatic conversion.
Tips for a High-Quality EPUB
Start with a text-based PDF
If words highlight individually in your viewer, you will get real reflowable text.
Remove unneeded pages
Blank pages and inserts end up in the book. Extract only the pages you need first.
Assemble the book first
If chapters are separate PDFs, merge them into one file to get a single book.
Lighten the images
High-resolution photos make EPUBs heavy and page turns slow. Compress the PDF first if it is large because of images.
Give the file a clear name
Rename the PDF to something like Author - Title.pdf before uploading. If the source has no title metadata, your library may otherwise show the book as scan_0042.
Adjust your reading app
Toggling the publisher styles option often fixes odd margins or fonts without reconverting.
Common Problems and Fixes
Only page images in the EPUB
The PDF is a scan. This converter has no OCR; use our PDF Reader with OCR (beta).
Page numbers and headers inside the text
Headers are ordinary text in a PDF, so an automatic converter cannot always tell them apart. Use the Word route or calibre's header removal if it bothers you.
Complex layout fell apart
Columns, sidebars and tables are simplified by design. Read such documents as PDF, or convert pages to images for phone viewing.
Protected, damaged or oversized PDF
Use Unlock PDF if you have the right to the document, Repair PDF for damaged files, and Split PDF for files over 100 MB.
