Redact PDF (truly erase)
Mark the regions to hide; the tool rasterizes the page then blacks them out — the text underneath is TRULY erased and cannot be recovered. Processed on your device, no file is uploaded.
Processed on your device — no file is uploaded to any server
Redacting a PDF lets you hide and truly erase sensitive information in a document — Vietnamese ID card (CCCD) numbers, account numbers, salary figures, addresses — before you send or publish it.
Unlike simply drawing a black box over the text (which recipients can still select and copy underneath), this tool rasterizes each page into an image and paints a solid black fill over the pixels, so the content beneath is permanently erased and can't be extracted from the result file. Everything runs right in your browser on your own machine — your files are never uploaded to a server.

Frequently asked questions
Does redacting a PDF send my file over the internet?
Everything runs right in your browser — your files are never uploaded to any server, keeping them completely private.
Can the text under the black boxes be recovered?
No. The tool rasterizes each page into an image and then paints a solid black fill over the pixels — completely different from just drawing a black box over the text (which can still be selected and copied). The result file contains only images, with no text layer or hidden area left to extract.
After redacting, can text in the file still be selected and copied?
No. The trade-off of truly erasing content is that the result file is image-based: you lose selectable text, links, and metadata. It's a good fit when you need absolute redaction on documents and application dossiers you send out.
