What happens to my PDF?

The document never leaves this browser tab for this tool. Your device performs the work with locally hosted PDF components. No login is required. We collect limited technical events but not document contents.

Can I use this tool on a mobile phone?

Yes, for compatible PDFs. Very large files and scanned pages may be slower or run out of memory on older devices. For heavy conversions, a desktop browser may be more comfortable.
