URL Encoder / Decoder
Encode or decode URLs and query strings. All processing happens in your browser.
What is URL Encoding?
URL encoding (percent-encoding) replaces special characters with a % sign followed by their hexadecimal value. This ensures URLs are transmitted correctly over the internet, as some characters have special meaning in URLs (like &, =, ?, #).
encodeURI encodes a full URL, preserving characters like : / ? # &. encodeURIComponent encodes everything, useful for query parameter values.
