Exploded paper layers reveal cyan geometry beneath a black redaction bar through a circular inspection aperture.

01 / THE FAILURE MODE

Covered is not removed.

Many redaction failures look perfect on screen. Underneath, the original text can still be copied, annotations peeled away, metadata read, or attachments opened. A visual check cannot prove structural removal.

RECOVERABLE TEXT LAYER

02 / THE AUDIT

Five structures. One honest verdict.

The app reads the PDF object graph locally and reports evidence by page. Uncertain cases stay marked for review.

  1. 01

    Covered & invisible text

    Finds text painting behind redaction annotations and opaque rectangles, plus invisible render mode.

  2. 02

    Metadata

    Flags document info and XMP packets that can reveal authors, dates, software, and workflow details.

  3. 03

    Annotations & forms

    Surfaces removable comments, unapplied redaction marks, and retained field values.

  4. 04

    Attachments & actions

    Detects embedded files, name trees, automatic actions, and active content.

  5. 05

    Audit identity

    Hashes the exact source and sanitized copy with SHA-256 in a portable JSON report.

03 / LOCAL WORKFLOW

From uncertainty to a reviewable artifact.

Proof, with limits stated.

Redaction Proof is a technical inspection, not legal advice or a guarantee. Unusual clipping, transformed text, and secrets baked into images still require visual review. The report keeps those limits attached to the result.
