- Can this tool remove a password from any PDF?
- Only if you know the password or the PDF's owner permissions allow it. This tool cannot crack unknown passwords — it removes the password from PDFs that are already accessible to you.
- Is my PDF uploaded to a server?
- No. All processing happens in your browser using PDF-lib. Your document never leaves your device.
