URL Encoder & Decoder
Percent-encode or decode URLs and query strings.
About the URL Encoder & Decoder
Encode strings so they are safe inside a URL, and decode percent-escaped text back to readable characters. Component mode escapes everything reserved; full-URL mode preserves structural characters like /, ?, and &.
