PDF Redaction Guide

Redact PDF Files Online

ClearKitPDF lets you manually select sensitive areas in a PDF and create a separate redacted document. The exported document is rebuilt from rendered page images so the original page text layer is not carried underneath the redaction.

How to Redact a PDF

  1. Upload the PDF you are authorized to edit.
  2. Drag over each sensitive area you want to redact.
  3. Review the marks and use Undo, Redo, Delete, and page navigation as needed.
  4. Apply the redactions and create the new PDF.
  5. Open the exported PDF and verify every redaction before sharing it.

Does PDF Redact Use AI?

No. This tool uses manual visual selection and deterministic browser-based processing. No AI generation is added to PDF Redact.

Frequently Asked Questions

Can I redact multiple areas?

Yes. Add multiple redaction areas on the same page or across different pages before exporting.

Is my original PDF changed?

No. ClearKitPDF creates a new PDF and keeps the original file unchanged in your browser.

Will the redacted text remain underneath the black area?

The export is rasterized page-by-page and the redaction marks are burned into the page image, so the original PDF text/vector layer is not copied into the output.

Will text remain selectable after redaction?

The security-focused export is image-based, so text selection and search may not work in the exported PDF.

Always verify the exported document

Reopen the new PDF and inspect every sensitive area before sharing, submitting, or relying on it for a legal or compliance purpose.
