Free Security & Privacy Tools
Add or remove password protection, redact a PDF so the text is genuinely gone, strip the metadata your files carry without telling you, and clear macros out of Office documents. Every job runs in server memory and nothing is written to disk.
Frequently Asked Questions
Can you recover a password I have forgotten?
No. The unlock tools remove protection from a file once you supply the correct password; they do not crack, guess or brute-force it. If the password is genuinely unknown, the file cannot be opened here. We deliberately do not offer password cracking.
Is the password I type stored anywhere?
No. The password is held in server memory for the few seconds the job runs, alongside the file itself, and is discarded together with it. It is never written to disk and never written to a log. Our logging code has no notion of a password field at all.
What encryption is applied when I protect an archive?
AES-256 in both cases, but there is one important difference. A 7Z archive can also encrypt its headers, so the names of the files inside are hidden as well. A ZIP always leaves its file listing readable even when the contents are encrypted, which is a limitation of the ZIP format rather than of this tool.
How is removing a macro different from re-saving the file?
The macro removers operate directly on the document container rather than re-rendering it. The VBA project and any Excel 4.0 macro sheets are deleted and every other part of the file is copied through byte for byte, so formulas, formatting and layout are untouched. The result is then re-inspected, and if any macro trace is still detected the job fails rather than returning a file we cannot vouch for.
Does redacting a PDF really delete the content?
Yes, and there are two modes. Precise mode removes the marked content itself and sanitises hidden metadata, leaving the rest of the document as real, selectable text. Image mode additionally flattens every page to a raster so that no text layer can survive anywhere in the file. Neither mode simply draws a black rectangle over the text.
Why was my file refused?
Every upload is validated before anything is processed, and files that present a real risk are refused rather than converted. The usual causes are an archive containing executables or scripts, a document with an embedded macro where the tool does not expect one, or a file whose internal structure does not match its extension.
Do these tools work without an account?
Yes. Every tool on this page is free and requires no registration. Files are processed in server memory and are never written to disk, so nothing is retained after the result is delivered.
