No. Only DRM-free books can be opened.

Can I make a MOBI or AZW3?

Modern Kindles and the Send to Kindle service accept EPUB directly, so EPUB is the output to use for Kindle.

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
