JWT Generator

JWT Generator is a free, browser-based tool built for one job: create jwt tokens for testing and development. It is part of ToolsMonk's developer tools collection, so you can finish the work without downloading software, creating an account, or jumping between multiple websites.

This tool is especially useful for workflows such as generating a test jwt for development and api testing, learning how jwts are structured and signed, and creating a token with specific claims to test an endpoint. Because it runs directly in your browser, you can use it on desktop, tablet, or mobile while keeping the process fast and easy for one-off tasks as well as repeat work.

JWT Generator builds and signs a JSON Web Token from a header, payload, and secret, a handy tool for testing authentication flows, experimenting with claims, and learning how JWTs are constructed.

A JWT has three parts, header (algorithm), payload (claims), and signature, and this tool encodes the first two and signs them with your secret to produce a complete token. It's the counterpart to the JWT Decoder: generate a token here, decode it there to inspect its structure.

Use it strictly for development, testing, and learning. Real production tokens should be issued by your authentication server, which handles secrets, expiry, and signing securely, and you should never paste a real production signing secret into any tool (use a test secret; generation here is local, but the habit matters). When a generated token fails server verification, it's almost always a secret/algorithm mismatch or missing required claims.

A core security reminder: a JWT payload is encoded, not encrypted, so it's readable by anyone holding the token, never put passwords or secrets in the claims. Generation runs entirely in your browser. Pair it with the JWT Decoder and the other ToolsMonk developer tools.
