How it works

Questions

Are my files uploaded?

No. Conversion uses the decoding and encoding built into your browser, and nothing is sent to the server. Open the Network panel in devtools to check for yourself.

Why is there no signup?

The server only serves a static page; it never touches your files. Without accounts there is nothing to log in to.

Can it handle batches?

Yes. Drop a batch, pick a target per file, then download individually or as a single zip.

Can I publish the generated HTML?

Yes. Styles are inline on the elements, so no external CSS is needed. It is a rendered document, not a site template.
