Can I unlock a PDF without knowing the password?
No. This free unlock PDF online tool requires the correct password to decrypt the file. It is not a password cracker. You must know the password that was used to protect the PDF. Modern AES‑256 encryption is practically impossible to break without the original password.

What types of PDF encryption are supported?
The tool supports AES‑256 encryption (PDF 2.0 standard, V=5 R=6) and RC4 40/128‑bit encryption (legacy V=1‑2 R=2‑3). It accepts both user and owner passwords — enter either one to unlock the file.
Is there a limit on file size or number of unlocks?
You can unlock PDFs up to 100 MB, as many times as you want. This unlimited PDF password remover has no daily caps, no hidden fees, and no premium tiers.
Does unlocking a PDF change the document content?
No. The tool removes only the encryption layer. The document content, layout, images, and text remain exactly the same. You get an identical PDF — just without the password prompt.
