How to use Redaction Checker
- Choose a PDF.
- Select Check for failed redactions.
- Open each finding to see the page and the boxes involved.
- If something was found, remove the content with Redact PDF and check again.
What to expect
The file is only read. Nothing is changed or uploaded.
- A clean result is not a certificate of safety: text can also hide in metadata, layers, attachments, form fields, images and old file versions.
- Dark labels with white text can be reported as possible leftovers; always look at the page.
- Image pages cannot be checked for underlying text. Rotated text positions are approximate. Up to 80 pages per run.
Frequently asked questions
Does it prove my redaction is safe?
No. It only reports what these checks found. Treat a clean result as one signal, not as proof.
Is my PDF uploaded anywhere?
No. The PDF is processed by JavaScript in your browser. Only the website's own code and assets are downloaded, and you can check this in your browser's network panel.
Do I need to create an account?
No. Every tool works without sign-up or login.
Is it safe for confidential documents?
Files are processed locally in your browser and never uploaded. Close the tab or select Clear to release them from memory.
