URL Encoder & Decoder

Percent-encode text so it's safe inside a URL or query string, or decode an encoded URL back to readable text. Instant and UTF-8 safe — and it all runs in your browser, so nothing is sent anywhere.

Encode (text → URL-safe) Decode (URL → text)

Encode for a query value (encodeURIComponent) — uncheck to keep / : ? & = for a full URL

When to use which

encodeURIComponent (default) — for a single value you're dropping into a query string, e.g. ?q=your%20value. Encodes / ? & = too.
encodeURI (uncheck the box) — for a whole URL where you want to keep the structure characters like / : ? & = intact.
Decoding turns %20, %2F, +-style sequences back into readable characters.

Privacy: everything runs locally in your browser — your text never leaves your device.
