How URL Encoding Works
URL encoding, also known as percent-encoding, is a method of converting characters into a format that can be safely transmitted in a URL. URLs can only contain a limited set of characters from the ASCII character set. Any character outside this set must be encoded.
Encoding Formula:
Character → % + Hexadecimal value of the byte(s)Example: Space → %20 | & → %26 | = → %3D
Component Mode (encodeURIComponent): Encodes every special character including : / ? # [ ] @ ! $ & ' ( ) * + , ; =. Use this when encoding individual query parameter values.
Full URL Mode (encodeURI): Encodes special characters but preserves URL structural characters like : / ? # [ ] @. Use this when encoding a complete URL while keeping its structure intact.
For multi-byte characters like Hindi (मुंबई) or Japanese (東京), each byte of the UTF-8 representation gets its own percent-encoded value. So a single character may produce multiple %XX sequences.

What is URL Encoding and Why Does It Matter?
URL encoding is a fundamental mechanism of the web. Every time you click a link, submit a form, or make an API call, URL encoding works behind the scenes to ensure data is transmitted correctly. Without it, characters like spaces, ampersands, and non-Latin scripts would break URLs entirely.
Developers encounter URL encoding daily when building web applications, working with REST APIs, handling form submissions, or constructing query strings. Even non-developers need it when sharing links that contain special characters or debugging broken URLs in analytics platforms.
Understanding the difference between encodeURI and encodeURIComponent is essential. Using the wrong one is a common source of bugs — encoding an entire URL with encodeURIComponent will break the protocol and path separators, while using encodeURI on a query parameter value will leave dangerous characters unencoded.
