PDF redaction (rasterize)

Black out areas of a PDF for real — pages are re-rendered as images with the marked areas painted over.

The file stays in this browser. Marked areas are painted over at render time, then every page is rebuilt as a flat image inside a new PDF.

Up to 25 MiB and 30 pages, 64 marks per page. The output is raster pages — all text and vector content is replaced by images, so nothing underneath can be recovered from the file. Mark edges can leave content visible at the borders: preview the output and widen marks if needed. Encrypted PDFs are not supported.

How to use

  1. Choose a PDF.
  2. Drag rectangles over the areas to hide, per page.
  3. Rebuild and download the redacted PDF.

What it supports

Up to 25 MiB and 30 pages, 64 marks per page. Every page is rebuilt as a flat raster image — text and vector content are replaced, so marked content cannot be recovered from the file and text selection/search is lost. Mark edges can leave content visible at borders; verify the output. Encrypted PDFs are not supported.
