About Encode / Decode Tools
Why this site exists
Base64 and URL encoding turn up constantly in debugging, and the usual move is to paste the string into whichever encoder ranks first that day. That string is frequently a JWT, an API response, or a config fragment, which makes "whichever ranks first" a bad habit.
This site does the same conversions without a server, so the paste never leaves your machine.
How the tool works
Encoding, decoding, formatting, and hashing all run in your browser. No backend endpoint receives your input, which is the entire reason to use this instead of a server-side encoder.
Errors are reported precisely. If JSON fails to parse you get the position and the reason, not a red box that says invalid.
What accuracy means here
The encoders are Unicode-correct. Naive Base64 implementations break on non-Latin characters and emoji, silently producing wrong output, so these round-trip multi-byte input properly and that behavior is tested.
