Free online EPUB to AVI converter

An EPUB is an e-book, so converting it to AVI is useful when a video player or editing workflow needs its pages as a timed slideshow. The conversion renders pages as images; it does not turn the book’s text into narration or animated video.

What the EPUB format is

EPUB is a reflowable e-book format used for novels, manuals, and other digital publications. It is created by publishing tools and word processors with EPUB export, and is commonly opened in Apple Books, Adobe Digital Editions, and e-reader apps. Its layout can change with screen size and reader settings.

What the AVI format is

AVI is a video container that can hold video encoded with different codecs. It is useful with older playback and editing software that expects AVI files. Compatibility depends on both the AVI container and the codec inside it; MPEG-4 Part 2 is one option for broad support.

How to convert EPUB to AVI

The conversion makes a video from rendered book pages. Set how long each page appears, then create the AVI from those pages.

1. Upload one or more EPUB files; the page displays the per-file size limit.
2. Set Show each page for to choose the page display duration, then start the conversion.
3. Download the resulting AVI file or files.

Offline with desktop software

Use Calibre to render the EPUB as PDF, Poppler’s pdftoppm to render PDF pages as images, and FFmpeg to assemble them into AVI. Calibre runs on Windows, macOS, and Linux; Poppler and FFmpeg are available for all three operating systems.

1. Convert the book to PDF with Calibre’s command-line tool: ebook-convert book.epub book.pdf. Check the PDF before proceeding because page breaks and layout depend on the EPUB and conversion settings.
2. Render the PDF pages to PNG images with Poppler: pdftoppm -png -r 150 book.pdf page. This creates numbered files such as page-1.png.
3. Assemble the numbered pages into an AVI. For five seconds per page, run: ffmpeg -framerate 1/5 -i page-%d.png -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2" -r 25 -c:v mpeg4 -q:v 4 -pix_fmt yuv420p book.avi. Change 1/5 to set a different page duration.

Quality and limitations

EPUB pages are reflowable, so the PDF’s page layout may differ from the appearance in an e-reader. The AVI contains page images, not selectable text, working links, or the EPUB’s interactive features. Higher PDF rendering resolution can improve small-text legibility but increases image and video dimensions.
