How it works

Drop a PDF and navigate to a page with sensitive content.
Drag black boxes over everything that must disappear. As many boxes per page as you need, each removable.
Apply: every page is re-rendered as an image with the boxes burned in, and a fresh PDF is built with the document metadata stripped.
Download the redacted PDF.

What people use it for

Blacking out account numbers, salaries, or names before sharing a statement.
Preparing legal or FOI documents where hidden text must be genuinely unrecoverable.
Removing personal data from a PDF destined for a public archive.

Good to know

Redaction rasterizes: output pages are images, so the PDF loses selectable/searchable text. That is the price of redaction that cannot be undone.
All pages are rasterized (not just the marked ones) so no stray text layer or metadata survives anywhere in the file.
File size may grow on text-heavy documents, since vector text becomes an image.

Frequently asked questions

Why not just draw a black rectangle in an editor?

Because a drawn rectangle only covers the text. Anyone can select underneath it or delete the shape. News stories about "redacted" documents leaking come from exactly that mistake. Rasterizing destroys the data itself.

Can the redacted content be recovered?

No. The marked regions exist only as black pixels in a re-rendered image; the underlying text and the original metadata are not present in the output file.

Is the document uploaded for processing?

No, which matters more here than anywhere: the whole point is sensitive content, and it never leaves your browser.
