Redact a PDF region
Remove a visible region by creating a new image-only PDF. No account required. Processing stays in your browser.
Privacy and limits
Files are processed in this browser without uploads. Encrypted or digitally signed PDFs are not supported. Editing and conversion may change the document; always keep the original. Operations stop when memory limits are exceeded.
Get a useful result
Select a region on one page and inspect its edges in the preview. The output is rebuilt as images: review every page and look for repetitions of the data elsewhere. Keep the original separately and share only the reviewed copy.
A practical example
Mark a fictional detail on page 1. Check the new PDF: the region should be covered and the document converted to images without selectable text.
Can I redact by cropping a page or adding a watermark?
They are not equivalent operations: cropping may leave recoverable content and a watermark does not remove what is underneath. Redacting one region does not locate other personal information or guarantee anonymity. Rasterization loses selectable text and accessibility.
