  Convert JSON to YAML and back — with honest warnings about what changes.

  • Try:

  URL Encoder / Decoder

  Percent-encode, decode, and parse query strings — with per-component RFC 3986 rules.

  • Try:
  • url encoder decoder
  • url decode online

  Percent-encode a value for the position it actually lands in, decode one that came back mangled, or split a whole URL into its components and a decoded query-parameter table. Double-encoding, + vs %20, punycode hosts and repeated keys are named, not guessed. Pure client-side.
