Redact PDF Free, Without Sending the PDF Anywhere

Field notes

The editor accepts a local PDF, lets the user move through pages with a thumbnail sidebar, and provides separate blackout, edit/resize, scroll, delete, undo, and zoom controls. The page identifies pdf-lib, WebAssembly, and JavaScript as part of its implementation and says the workflow works on computers and phones. Its central distinction is between covering text visually and placing opaque rectangles into the PDF structure; the latter is presented as the permanent-redaction path.
