Redact PDF

Manual redaction with rasterized export. Draw blackout areas, then export flattened pages so covered text is no longer selectable.

About PDF redaction

This is manual redaction. It does not perform AI detection. Export creates new page images so blacked-out content is burned in and hidden text under the marked areas is not kept as selectable PDF text.

Tool details

  • Input: PDF
  • Output: Flattened PDF
  • Processing: In your browser
  • Trade-off: Larger output, text becomes image

About Redact PDF

Manual Redact PDF lets you draw reviewed blackout areas and exports flattened page content so the covered source text is not preserved as selectable PDF text.

Choose the right tool: Use this page for manual control. AI Redact PDF can suggest likely PII, but every suggestion still requires review.

Important limitations

  • You must review every page and confirm each selected area.
  • Redaction does not remove sensitive information outside the marked regions.

File handling and privacy

Selected files are processed in your browser and do not need to be uploaded to Nexynto Tools servers.

Redact PDF FAQ

Is drawing a black rectangle enough to redact text?

A simple overlay can leave text underneath. This tool exports flattened redacted pages so covered text is not retained as selectable content.

Can I choose each redaction area manually?

Yes. Draw and review the areas that should be removed.

Does the tool automatically find personal data?

No. Use AI Redact PDF for suggestions, then review all proposed areas.

Should I inspect the exported PDF?

Yes. Confirm the visible result and test that redacted text cannot be selected or searched.

Is manual redaction uploaded?

Selected files are processed in your browser and do not need to be uploaded to Nexynto Tools servers.

How to permanently redact a PDF

Mark every sensitive region, review each affected page, then apply redaction. The output pages are rasterized so covered source text is not retained.

  • Keep the original in a secure location
  • Check headers, footers, and repeated values
  • Verify extracted output text before sharing

Redaction vs blacking out text

A visual rectangle can leave selectable text underneath. Secure redaction must remove or flatten the underlying content.

  • Do not rely on drawing annotations
  • Search the final output for sensitive phrases
  • Review visual context that could reveal removed information

Tool-specific FAQ

Is drawing a black box enough?

No. Preview boxes are only selections. The export rasterizes pages with the regions applied.

Can redacted text be selected afterward?

The rasterized output contains page images rather than the original text layer. Verification also checks extracted text.

Does redaction use OCR search?

Manual regions are supported. Automatic text-search redaction is not exposed because the current engine does not provide reliable coordinate matching.
