Can PDFly recover a forgotten password?

No — and no legitimate tool can. Modern PDF encryption (256-bit AES) is mathematically infeasible to brute-force without the password. PDFly's Unlock tool only removes the encryption when you supply the correct password, the same way Adobe Acrobat does. If you don't know the password, your options are: (1) ask the person who created the file, (2) check your password manager, or (3) accept that the file is unrecoverable. Tools that claim to "crack" PDF passwords either rely on common-password dictionaries (which fail against any decent password) or are scams.

Are my files private when I unlock them here?

Yes — Unlock runs entirely in your browser via pdf-lib. Both your PDF and your password are processed locally; the unprotected output is built client-side and downloaded directly to your device. Nothing is uploaded — your password never leaves your computer, and PDFly never sees the file contents. The original encrypted file on your disk remains untouched.

What if my PDF has only a permissions password (no opening password)?

PDFs with only a permissions password (the kind that opens fine but blocks printing or copying) can still be unlocked through the same Unlock flow — supply the owner password and PDFly removes both the encryption layer and the permissions restrictions. The output PDF behaves like an unrestricted file: you can print, copy, edit, and fill forms freely. If you don't know the owner password but the PDF opens without prompt, you can also use the Unlock tool with an empty password field — for some PDFs this is enough to clear the permissions, since they were never encrypted in the strict sense.

How to remove a password from a PDF

Take a password-protected PDF you already have the password for and save an unprotected copy — easier to print, share, or attach without re-typing the password every time. PDFly does the decryption in your browser; the file and your password never leave your device.

Removing a password makes sense when the secrecy is no longer needed — the contract is signed and going to internal records, the bank statement is being added to a finance folder, the protected report is moving to a shared drive where access is already controlled. Re-typing the password every time you open the file is friction; storing it in plain notes is risky. Stripping the password is cleaner.

PDFly's Unlock tool needs only the password you already know. The decryption runs in your browser via pdf-lib; the file and the password are processed locally, never sent to a server. The output is a standard PDF identical in content to the original but without the encryption layer. **PDFly cannot recover forgotten passwords** — for that, you need the original creator, not a tool.

1
Step 1 — Open the Unlock tool
Open the Unlock tool. The upload screen titled "Unlock Password-Protected PDF Files" is where you drop the password-protected PDF.
2
Step 2 — Upload your PDF
Click "Select PDF files" and pick the locked PDF — or drop it onto the page. The password input appears in the sidebar after upload.
3
Step 3 — Enter the password
In the sidebar, type the password into the "PDF Password" field. The password must match exactly — capitalization, spacing, and special characters all count. PDFly checks against the file as you go: a wrong password fails fast with a clear message rather than producing a garbled output.

Step 4 — Unlock and download
Click "Unlock PDF". PDFly verifies the password locally, strips the encryption layer, and saves an unprotected copy to your Downloads folder. The new file opens in any PDF viewer without prompting for a password — but the original on your disk is still encrypted.
