URL Encode

Encodes special characters using percent-encoding (encodeURIComponent). Safe for use in query string values.

Runs entirely in your browser

How it works

URL encoding uses the browser's built-in encodeURIComponent and decodeURIComponent functions. Query string parsing uses the native URLSearchParams API. Everything runs locally using browser-native APIs.

Your data stays local

All encoding, decoding, and parsing happens inside your browser tab. The URLs and query strings you enter are never sent to a server.

Frequently asked questions

What is URL encoding?

URL encoding (percent-encoding) replaces unsafe characters with a % followed by two hex digits, e.g. space becomes %20.

What's the difference between encodeURI and encodeURIComponent?

encodeURIComponent encodes all special characters including & = + — use it for individual values. encodeURI leaves URL-structural characters like / ? & intact.

Is my data sent to a server?

No. Encoding uses JavaScript's built-in encodeURIComponent in your browser.
