Frequently asked questions
Are my files uploaded?
No. PDF Fox processes files with JavaScript inside your browser. Nothing is sent to a server, so your documents stay private.
Is it really free?
Yes — no sign-up, no watermark, no page limit. Very large files are limited only by your device's memory.
Can I merge password-protected PDFs?
Unlock them first; encrypted PDFs can't be reliably combined.
