What is URL encoding?

URL encoding converts special characters (spaces, &, =, etc.) into a percent-encoded format (%20, %26, %3D) that is safe to use in URLs.

When do I need to encode a URL?

When passing query parameters that contain special characters, or when embedding a URL inside another URL.

Is my data stored anywhere?

No. All processing happens in your browser. Your data never leaves your device.

Is my data sent to a server?

No. URL encoding and decoding uses JavaScript's built-in encodeURIComponent() and decodeURIComponent() functions running in your browser. Your URL strings are processed entirely locally.
