The OpenRedakt project library: recent projects with their file counts and review status, library views such as Needs review and Exported, and a project to continue. Project names, folder paths and file names are blurred.

Why review matters

Information moves. Risk follows.

A name on a scanned page or a few seconds of speech travels with every copy you send: to courts, regulators, requesters and the public. One missed detail goes wherever the file goes.

Why hiding is not the same as redaction

01Document redaction

Find it. Review it. Redact it.

Open PDFs, scans and office files. Where detection is configured, findings wait for your decision. Anything else you mark yourself, by selecting text or drawing an area, with a reason on every mark.

  • Text and area marks
  • A reason on every mark
  • OCR for scans when configured
Explore document redaction
The OpenRedakt document workspace with no document open: the manual redaction panel with selection modes and reasons, the page tools, and the project panel listing files with their preparation status. Project and file names are blurred.

02Audio redaction

Every second matters.

Spoken detail lives in a moment. Select the exact range on the waveform, or type its start and end, choose a masking effect and, where supported, preview it before a new file is rendered.

  • Waveform and timeline review
  • Mute, tone, silence or noise
  • Preview before export
Explore audio redaction
The OpenRedakt audio workspace: masking effects and range controls beside a recording's waveform, transport controls and timeline. File names in the side panel are blurred.

Workflow

From sensitive to shareable.

The same three steps for every document and recording.

Add documents or recordings to a project. Supported office files are prepared as PDFs, and each file shows whether it is ready.

Why OpenRedakt

Built for the review, not just the redaction.

Every mark is a decision

Detection proposes. A reviewer accepts, rejects or adds marks and time ranges before anything is exported.

Documents and audio, one application

PDFs, scans, office files and recordings are reviewed in the same app, each on the surface it needs: a page or a waveform.

A record of what was redacted

Optionally write a machine- and human-readable report of what was redacted alongside the export. It never quotes the redacted text.

On your desktop, in your folders

OpenRedakt is a Windows desktop application. Each export is written as a new file to a folder you choose.

How OpenRedakt describes its limits

Use cases

Prepare sensitive records for the next step. Guides by sector.

Teams use redaction when records need to move into filing, disclosure, release, research, or controlled internal review.

Browse the industry guides

Law and the public record

Disclosure, filing, and release decisions that may be challenged, published, or relied on as evidence.

Patients, students, and employees

Records about individuals where other people named in the file must be protected too.

Financial and claims records

Dense identifiers, account data, and supporting evidence shared with auditors, counterparties, and courts.

Media and data reuse

Recordings and source material prepared for publication or other authorized downstream use.
