How do I decode a JWT token to text?

JWT tokens have three parts separated by dots. Copy the first part (header) or second part (payload) and paste it here. The tool will decode it to show the JSON text.

What if my Base64URL string has no padding?

That's normal for JWT tokens and many Base64URL uses. This tool handles Base64URL strings with or without padding (=) characters automatically.

Why does my decoded JWT show JSON?

JWT headers and payloads are JSON objects that have been Base64URL-encoded. When you decode them, you see the original JSON text.

Can I decode regular Base64 with this tool?

This tool is optimized for Base64URL (with - and _). For standard Base64 (with + and /), use the Base64 to text converter.

Is Base64URL to text the same as Base64URL decode?

Yes. 'Base64URL to text' is just a more search-friendly way to describe Base64URL decoding.
