Short answer
Cloud redactors see your file. Here, redaction runs in your tab: draw boxes, apply, download. Pages with boxes are rebuilt so text under black is removed, not just covered. Verify with the privacy checker before you share.

- 2
Drag boxes over sensitive areas (click a box to remove it).
- 3
Apply redaction, review, then download.
Files never leave your device
Your PDF is processed in this browser tab. Files never leave your device, and mypdf.space does not receive uploads. No account, no watermark, no server-side copy.
Limits worth knowing
- Redacted pages become images — text on those pages is no longer selectable.
- Automatic PII detection is a separate tool.
- Metadata and attachments need Deep Clean separately.
Frequently asked questions
Can I redact a PDF without uploading it?
Yes. This page runs entirely in your browser — no account and no server upload.Is a black box enough?
No. A shape on top leaves text in the file. This tool rebuilds redacted pages so the text is destroyed.How do I verify redaction worked?
Try selecting the blacked-out area, search for the old text, or run the PDF privacy checker.
