FAQ
Is there a limit on files or size?
No fixed limit: everything runs on your device, so it depends only on its memory.
Will the quality change?
No. Pages are copied as they are, text stays selectable.
Is it safe? Are my files uploaded?
No. The conversion runs entirely in your browser using WebAssembly. Your files are never sent to a server, so they stay private — you can even use the site offline after it has loaded.
