Redact PDF Online — Permanently Remove Sensitive Content

Need to redact a PDF before sharing it — hiding a social security number, an account number, or a name? This tool draws solid black boxes exactly where you want, then permanently rasterizes those pages so the covered content is gone, not just hidden underneath a shape. Pages with no redaction boxes are left completely untouched, at full original quality. Everything runs locally in your browser — nothing is ever uploaded.

How to Redact a PDF

  1. Open your PDF — Drop your PDF onto the editor or click to browse.
  2. Draw redaction boxes — Click and drag directly on the page to draw a black box over anything you need to remove.
  3. Repeat across pages — Navigate between pages and add as many boxes as needed.
  4. Download — Click Download — only the pages you marked are flattened to remove the underlying content; every other page stays at full quality.

Features

Truly Permanent

Redacted pages are flattened to a flat image, so there is no selectable text or vector data left underneath the black boxes — unlike a simple cover-up.

Untouched Elsewhere

Only pages with at least one redaction box are flattened. Every other page keeps its original text, fonts and quality.

Draw Anywhere

Click and drag directly on the page — draw as many boxes as needed, on any page.

100% Browser-Based

All processing happens in your browser. Your PDF never touches a server.

Frequently Asked Questions

Is this different from just drawing a black box in Edit PDF?

Yes — this is the key difference. Edit PDF's shapes are drawn on top of the page as a visual cover; the original text underneath is technically still present in the file and can potentially be recovered. Redact PDF instead flattens the entire page to a picture, so there is no original text or vector content left underneath at all.

Will pages without any redaction boxes lose quality?

No. Only pages that have at least one redaction box drawn on them are flattened to an image. Every other page in the document is left completely unchanged.

Can I undo a redaction box?

Yes, before downloading — click the small × on a box to remove it, or use Clear Page to remove all boxes on the current page.

Does it work on encrypted PDFs?

Yes — encrypted PDFs are rendered the same way this tool already flattens marked pages, so redaction works the same either way.
