PDF to EPUB for Kindle
Why PDF manga reads badly on e-ink, and how to get a Kindle-ready EPUB instead.
A free account takes PDFs. You don't need a card, and there's nothing to install. After your free volume it's $29 once, not per volume, and it doesn't renew.
If your pages are in a CBZ, ZIP or image files, convert them here for free.

PDF is a print format: it fixes each page to a paper size and tells the reader not to touch the layout. On a Kindle that means letterboxed pages with thick white margins, artwork shrunk to fit the wrong aspect ratio, no reflow, and sluggish page turns. High-resolution manga PDFs also go past the 50 MB Send to Kindle email limit. An EPUB sized for the device fixes that, and Send to Kindle accepts it.
The free browser tool below converts CBZ, ZIP, and image files. It doesn't accept PDF uploads yet. If your manga is already in one of those formats, convert it here for free. If it's in a PDF, a MangaSendr account handles it: each PDF page is rendered to a full-resolution image, trimmed and sized for your Kindle, packaged as an EPUB, and emailed to your Kindle. Your first volume is free.
Questions
Can I upload a PDF to the free converter?
Not yet. The free tool accepts CBZ, ZIP, JPG, PNG, and WebP. PDF conversion is part of MangaSendr: upload a PDF and each page is rendered to an image, trimmed and sized for your Kindle, and packaged as a Kindle-ready EPUB.
Why does PDF manga look bad on Kindle?
PDF pages are fixed to print dimensions, so the Kindle letterboxes them, with white margins on every side and shrunken artwork. There is no reflow, zooming on e-ink is slow, and large image-heavy PDFs often exceed the 50 MB Send to Kindle email limit.
Is EPUB better than PDF for Send to Kindle?
For manga, yes. Send to Kindle accepts both, but a PDF keeps its print page shape and margins. A fixed-layout EPUB built from page images sized for the screen fills more of it.
