How it works

Drag rectangles over content you want to remove. Output is rasterized, so redacted content can't be recovered by selecting or unhiding.

Many "redaction" tools just add a black rectangle annotation on top of the text, which the next person can move out of the way or strip in seconds. This tool does it properly: each page is rendered at 2x scale, your black rectangles are drawn on the raster, and that flattened image becomes the page. The original text and structure are gone from the output, you can't select around or under the boxes. Navigate page-by-page with the arrows, drag boxes onto each page, use Clear page to start over on the current one. When you hit Apply redactions, the whole PDF rebuilds with every page rasterized (so you'll lose selectable text on non-redacted pages too, an acceptable trade-off for the security guarantee). For high-stakes redaction (legal, regulatory), still review the output with a tool you trust. Built on pdf.js + pdf-lib.

How to use it

1. Drop your PDF. The first page renders as an editable preview.
2. Draw redaction boxes. Drag black rectangles over the content to remove; use the arrows to move between pages.
3. Apply redactions. Every page is rasterized with the boxes burned in — the original text is gone from the output.
4. Verify and download. Download the redacted PDF and review it; for legal work, double-check with a validated tool.

Frequently asked questions

Can the redacted content be recovered?

No. The output rasterizes every page and burns the black boxes into the image. The original text bytes are not in the new PDF.

Why does the whole PDF become rasterized, not just the redacted pages?

Uniformity. If only some pages were rasterized, the file would be a mix of vector and raster, more confusing. And it guarantees no edge cases where the redaction is bypassed.

Is this safe for legal redactions?

It's safer than annotation-based tools, but for court filings and regulated workflows, always verify with a redaction-validated tool and a colleague. The tool removes the visual content; it can't promise the file has no other forensic traces.

Does my PDF get uploaded for this?

No. All redaction happens locally via pdf.js and pdf-lib.
