Frequently asked questions
Most formatter, encoder, JWT, and hash tools run entirely in your browser. A few network tools (API request builder, header viewer) must contact the URL you ask them to, by design.
Yes. Format, validate, and beautify JSON online with no signup required.
The JWT Decoder inspects header and payload in your browser. Never paste production secrets into any online tool you do not trust; prefer local decoding for highly sensitive tokens.
Use JSON Compare for structure-aware diffs, or Diff Checker for raw text comparison.
