Privacy

Your files

We can't lose, sell or leak your files, because we never receive them. Conversions run entirely in your browser; your books, manuscripts and comics are opened and saved on your own device and are never transmitted to us or anyone else. This isn't a promise about careful handling – there is no handling. Technical details here.

Analytics

We use Google Analytics to understand which tools get used and whether conversions succeed. What we record is deliberately boring: page views, and events like "a MOBI conversion completed" with a coarse size bracket. Never filenames, file contents, metadata from your books, or anything else derived from your files – the conversion happens in your browser, so that information never exists on any server to begin with.

Google Analytics sets cookies to distinguish returning visitors. If you'd rather not be counted, an ad blocker or Brave's shields will block it entirely, and every tool on this site works exactly the same with analytics blocked – conversions never depend on it.

Error reports

If a conversion crashes, the error message (the kind of failure, never file contents or names) may be reported so we can fix the bug. Reports are scrubbed before sending.

Cookies

Only the Google Analytics cookies described above – nothing of ours, no fingerprinting, and nothing tied to your files. Block them and the site works identically.

Your account

There are no accounts, so there's no account data. Nothing to delete, nothing to export.
