Redact PDF

Draw a box, and that content is gone — not covered. Any page with a redaction box loses all text selection and search on that entire page, not just the redacted area.

About Redact PDF

Permanently remove sensitive content.

Redact PDF draws a solid black box over content you choose, then rebuilds that entire page as a flat image — so what's underneath the box isn't just visually covered, it's gone from the file. This is different from drawing a box on top of existing content (which every other tool in this category typically does, and which leaves the original text or image still selectable and copyable underneath). The tradeoff: any page with a redaction box is rasterized entirely, so it loses all text selection and search — not just inside the box, the whole page. Pages with no redaction box are left completely untouched and stay fully searchable.

Clear sensitive fields on a form

Remove account numbers, addresses, or other fields before archiving or forwarding.

Sanitize a scanned document

Remove a visible detail from a scanned page's image directly.

Why Redact PDF

Built for people who care about their documents.

Genuine removal, not an overlay

The page is rebuilt as a flat image — there's no text or image data left underneath the box to recover.

Untouched pages stay untouched

A page with no redaction box keeps its original text, unchanged and fully searchable.

Runs on your device

Nothing uploads to a server — redaction happens entirely in your browser.

No surprises

You always know exactly which pages were flattened: the ones you marked, and only those.
