Convert MOBI to HTML

Yes — that is the point of converting out of MOBI. The output opens as a real document with live paragraphs, styles and tables rather than a frozen page image, so you can edit it directly instead of retyping. Heavily designed source layouts convert less cleanly than plain prose, so expect to tidy spacing on anything built on a complex grid. HTML is readable in every browser on every device with no software install, and it reflows properly on a phone screen.

Yes, and the MOBI would not have. Browsers ship a decoder for HTML and none for MOBI, so a MOBI link forces a download while an HTML renders inline. That is usually the deciding factor when the file is going onto a web page rather than into an application.

DRM, in almost every case. A protected MOBI is encrypted and tied to an account, and no converter can decrypt it — ours included. Files you created yourself, or bought from a DRM-free store, convert without any trouble at all. Amazon stopped accepting MOBI for new publishing in 2022, and the format cannot express modern CSS, embedded fonts or fixed layout.

Yes for Word, Markdown and plain text: edit and save the HTML, then convert it back with the matching converter on this site, for example /docx-epub/ for a Word file. RTF and HTML have no converter back to EPUB here, so save the file as DOCX in your word processor first.

Kindle / Kobo apply their own reader CSS on top of the MOBI's embedded styles. The HTML we produce reflects the MOBI's actual encoded styling, not the reader's overrides. That's usually what you want for editing — it shows what the publisher intended.

Yes. Nobody reviews the file, and uploaded MOBI files are never used to train any model, which matters for unpublished manuscripts. The upload and the HTML are deleted automatically about 24 hours after conversion.
