URL Encoder / Decoder

Percent-encode text so it's safe to drop into a URL, or decode an encoded URL back to readable characters. Spaces, ampersands, question marks, and unicode all get escaped to their %XX form so they don't break the query string or path.

Handy when you're building a link with query parameters by hand, debugging why a redirect URL is mangled, or reading an encoded value from a log. Encode full URLs or just a single query component — all locally in your browser.
