Os teus ficheiros nunca saen do teu dispositivo. Todo o procesamento realízase localmente no teu navegador.

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.
