JWT Decoder

Decode readable JWT headers and payloads locally without verifying signatures.

Browser-first and privacy-conscious

JWT Decoder

Decoded locally. This tool does not verify signatures or token trust.

How it works

siteIndex processes input directly in your browser whenever possible, which keeps the tool fast and keeps your data private.

For URL requests, the app validates the address and only allows public HTTP/HTTPS targets before running the check.
