Draw black boxes over anything you want hidden. On export, each page is flattened to an image with the boxes burned into the pixels — so the redacted text is physically destroyed, not just covered. Unlike most free tools, the hidden content can't be copied back or recovered. Everything runs in your browser.

Miten se toimii

Most free "redaction" tools just draw a black rectangle on top of the text — but the text is still in the file underneath and can be copied or recovered, which has caused real-world data leaks. This redactor does it properly: it destroys the hidden content.

1
Your PDF is rendered in the browser
pdf.js renders each page to an image so you can see and mark it. The file is read into memory locally — never uploaded.
2
You draw boxes over what to hide
Drag to draw a black box over any text, signature, or image you want gone. Boxes can be removed with a tap.
3
Each page is flattened to an image
On export, every page is re-rendered to a high-resolution image with the black boxes burned into the pixels, then assembled into a new PDF with pdf-lib. The original text layer is discarded entirely.
4
You download the redacted PDF
Because the output is image-based, the hidden content is physically gone — it cannot be selected, searched, or recovered.

Safe redaction is exactly the kind of task you should never upload. Everything happens on your device — ideal for lawyers, journalists, HR, and anyone sharing contracts, statements, or records. The trade-off: the exported PDF's text is no longer selectable, which is the price of guaranteed redaction.
