Files stay in your browser — nothing is uploaded.
Click and drag over the content you want to redact — you can add boxes on every page.

What it does
Draw boxes over the content you want hidden, then redact. Unlike tools that just draw a black rectangle on top of the original text, this rebuilds every page as a flattened image — so the covered content is genuinely gone from the file, not just hidden underneath.
How it works
Everything happens locally in your browser — your file never leaves your device. Because pages are flattened to images, the output PDF's text won't be selectable or searchable.
