Frequently Asked Questions
Is it safe to lock/unlock PDFs online?
Yes! With PdfVala, all encryption and decryption happens locally in your browser using WebAssembly. Your files and passwords never leave your device, ensuring complete privacy and security.
Can I unlock a PDF without the password?
No. You must have the correct password to unlock a password-protected PDF. This is by design to ensure security. If you've forgotten the password, there's no way to recover it.
What if I forget my PDF password?
Unfortunately, if you forget the password, you cannot unlock the PDF. Always store passwords securely using a password manager or secure note-taking app.
Can I lock a PDF that's already locked?
You'll need to unlock it first using our Unlock PDF tool, then lock it again with a new password.
Does password protection compress the PDF?
No, locking a PDF doesn't change its file size. If you need to reduce file size, use our Compress PDF tool before or after locking.
Can I lock specific pages only?
PDF passwords apply to the entire document. To protect specific pages, first use our Split PDF tool to extract those pages, then lock them separately.
