Why use this tool

Inspect JWT parts in the browser without sending tokens to a server.

JWT Decoder helps inspect claims and token metadata quickly.

It decodes only and does not validate signatures.

01Paste a JWT token.

02Review decoded header and payload.

Confirm the input is the format you intended.

Scan the result before using it in a document, URL, config, or message.

Copy only the output you need.

Does this verify signature validity?

No. It only decodes token content.

Format, minify, and validate JSON in one place.

Encode text to Base64 or decode Base64 to text.

Convert Unix timestamps and date strings instantly.
