When this tool is useful
Removing visible secrets from a shareable copy when loss of searchable text, vectors, links, forms, and accessibility is accepted.
How local processing works
A real local page preview records dragged rectangles as normalized coordinates. Every page is then rendered to pixels, matching areas are burned in, and a new image-based PDF is written locally.
How to use it
- Prepare Permanently redact PDF areas: Work from a copy and confirm every sensitive occurrence, multiple opaque masks, their editable percentage coordinates, page numbers, and the actual preview orientation including rotated pages. Keep the source unchanged.
- Apply Permanently redact PDF areas: Process locally in the browser. A real local page preview records dragged rectangles as normalized coordinates. Every page is then rendered to pixels, matching areas are burned in, and a new image-based PDF is written locally.
- Download and verify: Save under a new name. Search and extract text, zoom into every mark, inspect metadata and attachments separately, and ask a second reviewer to attempt recovery.
Important limitations
The output is intentionally rasterized and the covered pixels are not recoverable; selectable text, vectors, links, forms, signatures, annotations, and accessibility are lost or invalidated.
Verify the downloaded result
Search and extract text, zoom into every mark, inspect metadata and attachments separately, and ask a second reviewer to attempt recovery.
Private by design
Your files stay in this browser. The tool does not upload the source or output to our servers.
