Бесплатно PDF Redactor

Как это работает

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. 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. 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. 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. 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.
