Mac guide

How to redact screenshots on Mac before sharing.

The safest Mac screenshot workflow is simple: find sensitive data before the screenshot leaves your machine, cover it with opaque redaction, flatten the output, and share only the clean copy.

Step by step

  1. 1

    Bring in the screenshot

    Open, paste, drag, capture with Redaktr, watch a selected folder, or batch scan a group of images.

  2. 2

    Review findings

    Check API keys, tokens, PII, faces, QR codes, customer data, and custom policy terms before deciding what stays visible.

  3. 3

    Share the clean copy

    Export or copy a flattened, metadata-stripped image with active redactions applied. Keep the original separate.

What to check before sharing

Secrets

API keys, bearer tokens, JWTs, URL tokens, webhook secrets, credentials, and .env values.

PII

Email addresses, phone numbers, faces, card-like numbers, personal notifications, and profile details.

Business context

Customer data, account IDs, internal labels, confidential terms, codenames, private metrics, and QR codes.

Why not just use Preview?

Preview is useful for manual markup, but it does not act like a screenshot sanitizer. It does not scan for secrets, explain likely findings, manage policy terms, or build a repeatable review workflow for AI, Slack, support, docs, and public sharing.

Redaktr is built for the review step: scan locally, show possible leaks, let you adjust or draw boxes, and export a separate clean copy.

Best practice

If the screenshot contains sensitive data, use opaque redaction and a flattened export. Avoid relying on blur or pixelation for API keys, PII, credentials, or customer data.

Mac screenshot redaction FAQ

Can I redact screenshots with Apple's Preview app?

You can manually cover parts of an image in Preview, but Preview does not scan for API keys, PII, faces, QR codes, customer IDs, or custom policy terms before sharing.

What is the fastest safe workflow?

Capture or import the screenshot, let Redaktr scan locally, review the findings, add manual boxes for anything unique, and export only the flattened clean copy.

Should I keep the original screenshot?

Redaktr leaves the original untouched. Keep it if you need it privately, but share the cleaned copy when sending screenshots into AI, Slack, support tickets, email, docs, or public posts.
