Encoding & Token Tools
Your all-in-one encoding toolkit. Encode and decode Base64, inspect JWT tokens, and generate UUIDs — all in one place, entirely in your browser.
When to Use Each Tool
Base64
Use for encoding binary data as text, embedding images in CSS/HTML, or transmitting data through text-only channels like JSON or URLs.
JWT
Use to inspect authentication tokens, debug API auth issues, verify token claims (expiration, roles), or examine token structure.
UUID
Use for generating unique database IDs, creating resource identifiers, or when you need collision-resistant random identifiers.
Privacy note: All processing happens locally in your browser. Your data never leaves your device.
