Unlock PDF
Remove a password you know from a PDF, right in your browser. Strip open passwords and restrictions — no upload.
Overview
Unlock PDF removes a password you already know from a PDF and strips owner-password restrictions like no-printing or no-copying, entirely in your browser. Drop your file and the tool detects whether a password is needed to open it; enter the one you know, or strip restrictions directly if the PDF opens freely. Decryption runs locally with qpdf compiled to WebAssembly, so your document and password never leave your device. This is not a cracker — it can only remove a password you provide.
Key Features
- Remove a known open password
- Strip printing/copying restrictions
- Detects whether a password is needed
- Runs entirely in your browser
- No upload — fully private
Common Use Cases
- Stop Re-entering a Password — Remove the password from a file you open often so you're not prompted every time.
- Enabling Editing — Strip restrictions so you can annotate, merge, or compress a PDF that blocked changes.
- Allowing Printing — Remove a print restriction from a document you're authorized to print.
- Archiving — Store long-term documents without an open password you might forget later.
- Preparing for Other Tools — Unlock a PDF so tools that can't read encrypted files can process it.
How It Works
Open your PDF
Drop the protected PDF. The tool detects whether it needs a password to open.
Enter the password
If it's needed, type the password you already know. If the file only has restrictions, you can strip those directly.
