Mark what to remove

Drag across the page to mark an area (this works with a finger on phones), or add an area and move it with the arrow keys. Shift with the arrow keys resizes it; Delete removes it.

0 marked areas

Try an example

Search for 148.50 to mark both totals, then drag an area over the signature image. In the downloaded PDF, 148.50 cannot be found or copied, the image area is black, and the heading and the Keep this line text remain.

What to expect

Redaction removes the text under each marked area, erases the pixels of images inside it and fills the area with black. Text only partly inside an area is cut at the character level: check the edges in the preview. Before a download is offered, the saved file is checked: no text can be extracted from any marked area.

Annotations and form fields on pages with marks are flattened into the page first, so they are no longer editable there. Document properties, bookmarks, attachments and text on unmarked pages are not changed; remove sensitive document properties separately. Search finds text only; scanned pages need drawn areas.

Password-protected PDFs must be unlocked first. Up to 500 marked areas. Opening allows 45 seconds; redaction stops after two minutes. Rewriting a PDF invalidates digital signatures.
