What is URL encoding?

URLs are limited to a small set of safe ASCII characters. Any character outside that set — spaces, non-ASCII letters, reserved punctuation — must be percent-encoded as %XX, where XX is the byte's hexadecimal value. A space becomes %20, the "&" inside a query value becomes %26, and an emoji like 🚀 becomes %F0%9F%9A%80.

Encode vs. Component

  • encodeURI — encodes a whole URL. Leaves reserved characters (: / ? # & =) alone because they have structural meaning.
  • encodeURIComponent — encodes a single component (a query param value, a path segment). Encodes reserved characters too. This is what you want 95% of the time. Turn on "Component mode" for this behaviour.

Plus-sign quirk

HTML forms encode spaces as + instead of %20 (the application/x-www-form-urlencoded format). When handling form submissions or query strings, remember to replace + with a space before percent-decoding. Toggle "Treat + as space" to match form encoding.

Common use cases

  • Building safe links programmatically (search URLs, share URLs, deep links).
  • Decoding a URL copied from the browser address bar to read it in plain text.
  • Parsing query strings to extract analytics or tracking parameters.
  • Preparing values for REST API query parameters.
