How redaction works
Selected regions are permanently erased when the redaction pipeline is available, then filled black. Always verify search and copy on the downloaded file before sharing. For certified legal workflows, still use a dedicated compliance tool.
Before you share
- Search the downloaded PDF for the redacted words
- Try selecting or copying over the black boxes
- Keep an unredacted master offline
Redact PDF Online — Complete Guide
Permanently remove sensitive text, account numbers, and faces from PDFs before sharing. PdfPeaks Redact PDF erases selected regions (text operators and overlapping image pixels) and fills them black when the redaction pipeline is available. Always verify the downloaded file before sharing.
How It Works
Upload the PDF, draw black boxes over sensitive areas on the page preview, and apply. Download the redacted PDF and confirm covered text cannot be searched or copied.
- Step 1 — Upload: Open the PDF containing sensitive data.
- Step 2 — Draw regions: Click and drag on each page to cover text or images.
- Step 3 — Verify: Download and try selecting or searching the covered text — it should no longer be recoverable.
Security & Privacy
Files are encrypted in transit and deleted after processing — see our Privacy Policy for details.
Common Use Cases
- External shares: Remove SSNs, account numbers, or draft notes before emailing.
- Demos: Blank sample customer data before a presentation.
- Internal reviews: Strip fields that should not leave the team.
- Compliance: Regulated filings may still need dedicated legal redaction tools.
- Pair with Protect: After redacting, use Protect PDF if the file still needs a password.
Tips for Best Results
Always keep an unredacted master offline. Treat online redaction as practical privacy, not a substitute for certified legal workflows. Supported format: PDF (.pdf).
