Blaai deur lêers

Jou lêers verlaat nooit jou toestel nie. Alle verwerking gebeur plaaslik in jou blaaier.

Draw black boxes over anything you want hidden. On export, each page is flattened to an image with the boxes burned into the pixels — so the redacted text is physically destroyed, not just covered. Unlike most free tools, the hidden content can't be copied back or recovered. Everything runs in your browser.

journalism tips

🛡️

Names, signatures, and reference numbers can expose a source. True redaction removes them so they can't be recovered from the published file.

⚠️

Newsrooms have leaked source identities by publishing PDFs with removable black boxes — flattening prevents that.

🔍

Also run the document through the Metadata Remover to strip author and software fingerprints.

🔒

Everything runs locally, so sensitive source material is never uploaded.
