What is a PNG to EPUB converter?

A PNG to EPUB converter takes a PNG image and saves it as an EPUB ebook whose cover is that picture. People use it as an EPUB cover converter when they have cover art and need an .epub file, or when they want to convert a PNG to EPUB online. This page does that in the browser: you upload a PNG, add a title, and download an EPUB. The file has one page, the cover image, so an ebook reader can show the PNG as the book cover.

How to convert a PNG to EPUB

Three steps from a PNG cover to an EPUB file.

  1. Add the PNG

    Drop a .png cover image. The preview shows the picture that will become the book cover.

  2. Name the book

    Enter a title and, if you want, an author. The title is also the download name.

  3. Download the EPUB

    Click Download EPUB and open the file in an ebook app.

Tips for an EPUB cover

Get a cleaner cover book from a PNG.
  • 01

    Use a portrait image

    Ebook covers are usually taller than they are wide. A portrait PNG fills the cover view more naturally.

  • 02

    Keep the title in the picture

    The page shows the PNG itself. Put the title artwork in the image if you want it visible on the cover.

  • 03

    Stay under 15 MB

    A smaller PNG opens faster on a phone. Compress the image first if the file is large.

  • 04

    Open it in an ebook app

    The download is an EPUB, not a renamed PNG. Apple Books and Calibre read the cover from that file.
