How to blur a Slack screenshot
- Paste the Slack screenshot with Ctrl+V or drop it above.
- Emails, phone numbers, URLs, IP addresses and API keys are highlighted. Turn on AI to find colleagues' names and company names too.
- Use Find and redact to cover your workspace or company name everywhere, then drag boxes over avatars, the sidebar and any thread you don't need.
- Download as PNG or JPG and add it to your post, ticket or deck.
What a Slack screenshot can give away
A Slack screenshot rarely shows just the message you meant. The sidebar, the header and the thread around it tell people a lot about your company and who works there.
- The workspace name, and its URL if the browser address bar is in the shot
- Channel names in the sidebar, which can hint at unreleased projects, clients or incidents
- Colleagues' names, avatars and status messages
- Customer names, emails and order details pasted into support or sales threads
- Internal links: dashboards, docs, admin panels, staging URLs
- API keys, tokens and passwords pasted into dev channels
Where Slack screenshots end up
People share them in bug reports to Slack app and bot developers, in vendor support tickets, in conference talks and blog posts about how a team works, in social posts, and as evidence in workplace complaints. Each of these leaves the workspace, and anyone who sees it can zoom in.
What's usually fine to keep: the message you're showing, timestamps and generic channel names like general. Crop the sidebar out entirely if you don't need it. It's quicker than covering every channel, and you can crop the page in the editor before you export.
Keys and internal URLs get extra care
Tokens, including Slack's own, and private keys are found automatically. Cover them with Solid boxes rather than blur, and rotate any key that was ever visible in a shared screenshot. Hiding it afterwards doesn't undo the earlier exposure.
Private by design
The screenshot is opened, read and exported inside your browser tab. It is never uploaded, so nobody (including us) sees your chats or emails.
Questions
Can it hide my company name in every message?
Yes. Type the company or workspace name into Find and redact and every match on the screenshot is covered, including in links and channel names.
Are colleagues' avatars blurred automatically?
Avatars that show a face are usually detected. Logos, initials and cartoon avatars aren't faces, so drag a box over them, or crop the column away.
