Security Tools

3 tools

Three tools, and the strongest argument on the site for client-side processing. Two of them take a password, and every other password tool on the web asks you to upload a confidential document and then type its password into the same form — handing a stranger both the lock and the key in one action.

Why does it matter that these run in your browser?

Because of what you are submitting. Uploading a password-protected file to a remote service and typing the password alongside it hands over the document and the credential together, to infrastructure you cannot inspect, at the exact moment the document is sensitive enough that someone bothered to encrypt it. Here the file is read by the File API and the password is typed into a form field that no code transmits anywhere. Passwords are also cleared from the interface as soon as processing finishes, so they do not sit in memory or survive an autofill.

Is it legal to remove a PDF password?

Removing a password from a document you own or are authorised to access is ordinary file management — the everyday case is a bank statement, payslip or utility bill that arrives encrypted and needs to be filed unencrypted in your own records. Circumventing protection on someone else's document without permission is a different matter and may be unlawful where you are. These tools require the password: nothing here cracks, guesses or brute-forces anything, so they cannot open a document you do not have the credentials for.

What do you lose by unlocking a PDF here?

Normally, nothing visible or interactive: the primary unlock path removes the security handler without re-rendering, preserving selectable text, links, form fields, annotations, metadata, bookmarks and page dimensions. A PDF that cannot be re-serialised safely uses a local raster fallback instead; that keeps the visible pages but discards searchable text and interactive structure, and the result message says when this happens. The unlock page also publishes the equivalent qpdf command for people who prefer a command-line workflow.

Every tool in this category runs on your device

There is no upload step and no processing server. Open your browser’s network panel and run any of them — the only requests are for the page itself.
