URL Encoder / Decoder
Pre-loaded with the characters that break query strings — spaces, ampersands, percent signs, quotes, slashes — so you can see exactly how encodeURIComponent escapes each one. Paste anything, hit Encode or Decode, and the last action re-runs live as you keep typing. Malformed percent-sequences are handled leniently instead of crashing.
