Read a PDF on a Kobo as a real e-book

Kobo e-readers open EPUB files natively, so converting a PDF to EPUB gives you text that re-flows to the screen instead of fixed pages. Convert the PDF here, then copy the EPUB to the Kobo over USB.

Try five pages from your PDF before converting the full book.

Why convert instead of opening the PDF

A Kobo can open a PDF, but only as fixed pages: on a 6- or 7-inch screen that means zooming into every page. An EPUB is laid out by the reader itself, with your font, size and margins.

How to put the EPUB on a Kobo

  • Convert the PDF to EPUB here and check the free sample.
  • Connect the Kobo to your computer with a USB cable and copy the EPUB onto it.
  • Eject the device; the book appears in your library.

What the engine does with your PDF

  • Reads the position of every character and rebuilds the reading order, including multi-column pages.
  • Joins lines back into paragraphs and rejoins words hyphenated at the end of a line.
  • Removes running headers, footers and page numbers that repeat across pages.
  • Turns footnotes into linked notes and builds chapters from the PDF's outline or its headings.
  • Writes an EPUB 3 file and checks it with EPUBCheck.

FAQ

Does a Kobo read EPUB files?

Yes. EPUB is the Kobo's native e-book format.

Is it free?

Every file gets a free sample of up to 5 pages before you pay anything, so you can judge the result on your own book. The Free plan converts up to 100 pages a month; Pro and Business convert more.

Will the EPUB be perfect?

No converter can promise that, and we don't. When the engine detects problems (unreadable glyphs, doubtful reading order) it shows a warning instead of hiding it, and the sample shows you the hard parts before you pay.

What happens to my file?

Your PDF is deleted as soon as the whole book is converted, or 2 hours after its last conversion. The EPUB is deleted 1 hour after your first download, or 24 hours after it's ready. Files are never published, and never used for benchmarks or training without your explicit permission.
