Redaction Checker

Is the blacked-out text really gone, or still recoverable?

On your device. No watermark. No sign-up.

How to use Redaction Checker

1. Open your file. Redaction Checker starts as soon as you drop a file or click the box above — the file opens in your browser and stays there.
2. Choose your options. Drop your PDF in, set your password or scrubbing options, then download the protected or cleaned file.
3. Download the result. The finished file is generated on your device and saved straight from your browser — free, with no watermark added.

This tool is processed locally with JavaScript inside your browser tab. The document is not uploaded, stored or seen by a server, which makes it suitable for contracts, invoices, CVs and medical or financial records.
