FAQ
- How do I decode a JWT token?
- Paste your JWT token into Toollo's decoder and it will instantly parse and display the header, payload, and signature. It decodes the Base64 content and formats it as readable JSON.
- Can I verify a JWT signature with this tool?
- Toollo's decoder displays the algorithm and signature data from the token. It highlights expiration status so you can quickly see if a token is expired, but full cryptographic verification requires the signing key.
- Is it safe to paste JWT tokens into an online decoder?
- Yes, on Toollo it is completely safe. The decoder runs 100% in your browser and your tokens are never sent to any server. No data is logged or stored.
