About Bearer Token Parser

The Bearer Token Parser takes a full HTTP Authorization header, strips the Bearer scheme, and extracts the token — decoding its JWT claims when the token is a JWT. It's built for debugging API requests where you've copied a whole header and just need the token and its contents. Parsing happens in your browser, so nothing is uploaded. For a raw token, use the JWT Decoder, and to check expiry the JWT Expiration Checker.

Frequently Asked Questions

What input does it expect?

Paste the full Authorization header value, such as 'Bearer eyJ...'. The parser removes the scheme and works with the token itself, decoding it if it's a JWT.

Does it verify the token?

No. It parses and decodes for inspection only. Signature verification requires the signing key and belongs on the server, so treat the decoded output as informational.

Is Bearer Token Parser free to use?

Yes. Bearer Token Parser is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use Bearer Token Parser?

Absolutely. Bearer Token Parser runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
