Webtoon to EPUB Converter

Get vertical-scroll manhwa chapters you own onto a paginated e-ink screen.

Webtoons and manhwa are drawn for an infinite vertical scroll, while Kindles and other e-readers paginate. The bridge between the two is a fixed-layout EPUB where each image becomes one screen-sized page. Most webtoon archives are already stored that way — a CBZ or ZIP of the chapter cut into page-height segments — and those convert cleanly with the tool below: upload the archive, download the EPUB, send it to your Kindle.

One honest caveat: this free tool converts each image into exactly one page. If your chapter is saved as a single continuous strip thousands of pixels tall, that strip gets scaled to fit one screen and becomes unreadable — split it into screen-height segments first (or grab a release that's already segmented) before converting. Also note that the free tool outputs grayscale EPUBs tuned for monochrome e-ink; that's ideal for standard Kindles, while color devices are better served by MangaSendr's per-model presets.

Frequently Asked Questions

Can I convert a single tall webtoon strip?

You can upload it, but each image becomes exactly one EPUB page — a strip thousands of pixels tall gets scaled down to fit one screen and turns unreadable. Split the strip into screen-height segments first, or use an archive where the chapter is already cut into page-sized images.

Do webtoons work on black-and-white Kindles?

Yes. The free tool converts pages to grayscale optimized for e-ink, which reads well on a Paperwhite or any monochrome Kindle — color art comes out in shades of gray. For color output on devices like the Kindle Colorsoft, MangaSendr's per-device presets can preserve color.

What file should I upload?

A CBZ or ZIP of the chapter's images (JPG, PNG, or WebP), or a single image file, up to 200 MB. Pages are ordered by filename, so zero-padded numbering keeps the scroll order intact.
