Frequently asked questions
Is Unlock PDF free?
Yes. Unlock PDF is completely free with no sign-up and no watermarks.
Are my files uploaded?
Your PDF files are processed locally in your browser — they are never uploaded to our servers.
Is there a file size limit?
Free usage supports files up to 200 MB. Because processing happens on your device, very large files depend on your device's available memory.
Can this crack a PDF without the password?
No. You need the password to open an encrypted PDF. PDFs that open freely but block printing or copying can be unlocked without one.
