Encoding
Encode, decode and inspect text-based formats.
3 tools in this category Base64 — text Encode and decode UTF-8 text to and from Base64. Image ⇄ Base64 Convert an image to a Base64 data URL and back. JWT decoder Inspect a JWT — header, payload and expiration — without verifying.
Encoding tools turn data from one representation into another so it can travel safely through text-only channels. All of these run inside your browser tab — the text or image you paste never reaches a server.
