How to Blur or Redact Sensitive Info in a Screenshot Before Sharing

Screenshots leak more than people realise — a browser tab title, an email address, an order number, or an API token sitting in the corner. Before you share one publicly, it is worth taking a few seconds to redact anything sensitive.

What to hide

  • Personal data — names, emails, phone numbers, home addresses.
  • Account details — usernames, order or invoice numbers, account balances.
  • Secrets — API keys, tokens, passwords, session URLs.
  • Context clues — other browser tabs, notifications, or bookmarks in frame.

How to redact properly

Draw a solid box over each sensitive area — not a light blur. Heavy pixelation and mild blur can sometimes be reversed, so an opaque rectangle is the safe choice. The browser extension includes annotation tools to drop solid shapes on a capture before it ever leaves your machine, and our guide on how to annotate a screenshot walks through the markup.

Remember: a shared link is public

Any image you upload is reachable by anyone who has the link. Random, unlisted URLs mean strangers cannot enumerate their way to it — that is why sequential, guessable services are risky, as we cover in is prnt.sc safe — but the image itself is not private. So redact before uploading, not after.

Once your screenshot is clean, turn it into a link and share it anywhere. Free, no account, and your uploads stay anonymous.
