About This Tool
Decode and inspect JSON Web Tokens without installing anything. Paste a JWT and see the header, payload, and signature decoded and formatted. Checks expiration too so you know immediately if the token is still valid.
How to Use
- 1Paste your JWT into the input field
- 2View the decoded header and payload sections
- 3Check the expiration status and issued-at time
- 4Verify the signature if you have the secret key
Why Use This?
When you're debugging auth issues, you need to see what's actually in the token. Is it expired? Is the role claim wrong? Does the audience match? Decoding it manually is tedious — this shows everything instantly.
