Pro Tips

  • Microsoft's Safe Links wraps every link in incoming email with a redirect through Microsoft's own domain, which scans the destination when clicked - this tool just unwraps that redirect to show the real URL
  • This tool never actually visits or fetches the destination URL - it purely parses the wrapped link's query string locally, so it's safe to use even on a suspicious-looking link
  • The 'data' and 'sdata' parameters are internal Microsoft tracking tokens, not part of the actual destination
  • Always inspect the unwrapped URL carefully yourself before deciding whether to visit it - unwrapping doesn't mean the destination is safe

Most Popular

Most people paste a wrapped link from a suspicious-looking email to see exactly where it actually points before clicking it

When to Use This Tool

Checking a Suspicious Email Link Safely

See a wrapped link's true destination without clicking through Microsoft's redirect.

Sharing a Clean URL Instead of a Wrapped One

Extract the original short, clean URL instead of forwarding a long wrapped Safe Links URL.

Understanding What a Link Actually Points To

Decode a Safe Links URL to see the real destination it protects.

Auditing Email Security Configurations

Verify what Safe Links wrapping looks like for links in your organization's email.

How It Works

1

Parse the pasted URL and confirm its hostname belongs to Microsoft's safelinks.protection.outlook.com domain

2

Extract the 'url' query parameter, which contains the original, URL-encoded destination link

3

URL-decode that parameter to reveal the plain original destination URL

Frequently Asked Questions

Does this tool visit the link for me?

No. It only parses the wrapped URL's query string locally in your browser - it never sends a request to either the Safe Links redirect or the final destination.

Is a decoded URL guaranteed to be safe?

No. Unwrapping just reveals what Microsoft's Safe Links was protecting - it doesn't verify whether that destination itself is safe. Always evaluate the revealed URL carefully.

Why does the destination URL look garbled?

The original URL is percent-encoded inside the wrapped link's query string. This tool automatically decodes it back to a normal, readable URL.

Is my pasted link sent to a server?

No. All parsing and decoding happens locally in your browser.
