What this tool does
Encoder and decoder tools convert data between Base64, URL-encoded, HTML entities, ROT13, Morse code, binary, hex, and JWT formats. They handle both encoding (plain to encoded) and decoding (encoded back to plain).
Why use this tool
Web developers constantly encounter encoded data in APIs, URLs, tokens, and configuration files. Being able to decode a JWT payload or Base64 string instantly saves round-trips to the terminal or Stack Overflow.
How it works
Each tool applies a specific encoding algorithm to your input bytes. Base64 maps every 3 bytes to 4 ASCII characters. URL encoding escapes special characters with percent-hex pairs. JWT decoding splits the token at dots and Base64-decodes each segment.
Pro tip
When debugging JWTs, always check the "exp" (expiration) claim first. Most authentication bugs come from expired tokens, and the decoded timestamp is easy to overlook.
