About URL Encoding

URL encoding (percent-encoding) converts characters that are not allowed in URLs into a % followed by two hexadecimal digits. For example, a space becomes %20, & becomes %26, and = becomes %3D. This ensures URLs work correctly across all browsers and servers.

Component encoding (encodeURIComponent) encodes all special characters including ?, &, =, and / — used when encoding query parameter values. Full URL encoding (encodeURI) preserves URL structure characters like /, ?, &, and = — used when encoding a complete URL.

Frequently Asked Questions

%20 is the URL-encoded representation of a space character. URLs cannot contain spaces, so they must be encoded. You may also see + used instead of %20 in query strings (form submissions), but %20 is the standard.

Characters that must be encoded include spaces, &, =, ?, #, %, +, and non-ASCII characters like Hindi, Chinese, Arabic text, and symbols like ₹. Letters, digits, -, _, ., and ~ do not need encoding.

Use encodeURIComponent when encoding individual query parameter values (e.g. search terms, user input). Use encodeURI when encoding a complete URL — it preserves /, ?, &, = which are needed for URL structure.
