Turns EPUB, MOBI, AZW3 and PDF into whatever your e-reader actually opens.
The ebook corner of Online-Convert, which has been running since 2008. It converts between EPUB, MOBI, AZW3, FB2, LIT and PDF and — the part that matters — lets you pick the target device, so a Kindle file comes out with sane margins instead of a reflowed mess. Everything is uploaded and queued on their servers, and a busy afternoon means waiting.
Questions
A genuinely usable free tier with paid plans for volume or team features. Free conversions are capped by file size and a daily count, and DRM-protected books will not convert at all.
Yes. Online-Convert Ebook Converter sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
