When do I need URL encoding?

Whenever special characters appear in a URL – for example in search queries, query parameters, form data or links containing spaces, &, ?, = or accented characters.

Is my data sent anywhere?

No. Encoding and decoding happen entirely in your browser. Your input is not sent to the server or stored.

Q: What is URL encoding?

URL encoding (percent-encoding) converts special characters, spaces and accented letters into a URL-safe format (e.g. a space becomes %20). This keeps URLs and query parameters valid and correctly transmitted.

What is URL encoding?

URL encoding (also called percent-encoding) converts special characters into a URL-safe format. Characters like spaces, umlauts or special characters (& = ?) are converted to percent notation – for example, a space becomes %20 and & becomes %26. This is necessary for URLs to be transmitted correctly, especially in GET parameters, form values or API requests.
