FAQ
Can I unlock without a password?
For strong encryption, a password may be needed. This tool mainly removes editing/printing restrictions.
Is my file safe?
Yes — everything runs locally in your browser.
Can I unlock a PDF if I forgot the password?
If the PDF has an owner password (restricts editing/printing), yes. If it has a user password (requires password to open), you need the password first.
Will unlocking affect the PDF content?
No. Content, formatting, and quality remain identical. Only restrictions are removed.
Is this legal?
Yes, for PDFs you own or have permission to modify. Unlocking copyrighted documents without authorization may violate terms of service.
What encryption types are supported?
Supports 40-bit RC4, 128-bit AES, and 256-bit AES encryption used in PDF 1.3 through PDF 2.0.
