Microsoft Safe Links Decoder
Reveal the original destination wrapped by Outlook and Microsoft 365 Safe Links
About this tool
Microsoft Safe Links Decoder extracts the original destination from URLs rewritten by Outlook and Microsoft 365 Defender. Paste one or many safelinks.protection.outlook.com addresses and the tool follows nested url parameters without visiting the destination. The result identifies the target host, protocol, and number of wrapper layers so you can inspect a suspicious or inconvenient email link before opening it. Decoding occurs locally; the wrapped link and original target are not sent to a server.
Frequently Asked Questions
What is Microsoft Safe Links?
It is a Microsoft 365 security feature that rewrites email URLs so Microsoft can evaluate them when clicked.
Does decoding open the destination website?
No. The tool only reads the encoded url parameter and never requests the target page.
Can it decode nested Safe Links?
Yes. It follows up to five Safe Links wrapper layers and reports the depth.
Does a decoded URL mean the destination is safe?
No. Decoding reveals the destination but does not scan it for malware or phishing.
Can I decode several links at once?
Yes. Paste one Safe Links address per line.
Are the links uploaded?
No. URL parsing and decoding happen entirely in your browser.
