About this tool: Redact PDF
Apply a secure visual redaction by rasterizing the PDF pages, painting the selected region black and rebuilding a flattened PDF so the original underlying page content is not retained. Create a flattened PDF with a selected rectangular region permanently burned out on one page.
How it works
Every page is rasterized locally. The selected page receives a black redaction rectangle on the raster image before a new PDF is built from those images.
Practical example
Redact an account number region on page 1 by choosing its approximate x, y, width and height percentages, then download the flattened result.
Important notes
This removes underlying selectable page content by flattening the entire PDF, but it also removes links, forms and selectable text. Always inspect the downloaded result.
Privacy & processing
Rasterization and redaction run locally in the browser; the source PDF is not uploaded.
