How to redact a screenshot on Mac
A screenshot can expose an email address, customer name or account number even when the main message is harmless. Here is a repeatable way to protect the copy you share.
1. Capture only what you need
Choose an area or window rather than the full screen when possible. Before annotating, scan the screenshot edges, browser tabs, notifications and any visible customer records. A tighter capture reduces what you must protect later.
2. Use an opaque redaction for secrets
Open the screenshot in Snipfolio and place a redaction over every sensitive field. Extend the shape beyond the text, including punctuation and adjacent labels if they reveal the answer. Blur can make a presentation easier to read, but for credentials and personal data an opaque cover is the safer choice.
3. Export a flattened copy
Snipfolio keeps the source screenshot and editable marks in your local collection so you can revise them. An exported PNG and the images uploaded for a share link are flattened: the marks are rendered into the shared image. Do not send the editable project or an original screenshot when the original contains private information.
4. Verify the exact file you will send
Open the exported image at full size and zoom into every covered area. Check that no text remains visible outside the shape, and inspect the filename and metadata you intend to share. For a link, open the public view yourself before sending it. If the export is wrong, adjust the mark in the local collection and export again.
