SafeLink Decoder

What is a SafeLink Decoder?

Microsoft Defender for Office 365 SafeLinks is a security feature that protects users from malicious URLs by rewriting links in emails and Office documents. When you click a SafeLinks-protected URL, it first passes through Microsoft's安全检查 before redirecting you to the actual destination. A SafeLink Decoder extracts the original destination URL from these rewritten links, allowing you to see where a link actually leads before clicking.

This online SafeLink decoder tool instantly parses Microsoft SafeLinks URLs and reveals the underlying destination. Simply paste a SafeLinks URL and the tool extracts the original URL from the url query parameter. All processing happens in your browser, and no data is sent to any server.

How to Use the SafeLink Decoder

• Copy a SafeLinks URL: From an email, get the full SafeLinks URL (it typically contains safelinks.protection.outlook.com).
• Paste it: Paste the SafeLinks URL into the input field.
• View the decoded URL: The original destination URL is displayed instantly.

Why Use a SafeLink Decoder?

• Security Awareness: Verify where a link actually leads before clicking.
• Link Analysis: Analyze SafeLinks-protected URLs for phishing or malicious destinations.
• Troubleshooting: Debug issues with SafeLinks rewriting rules and URL redirection.
• Privacy: All processing is client-side, so your links remain private.
