What is URL encoding?

URL encoding (also known as percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). It replaces reserved and non-ASCII characters with a "%" symbol followed by two hexadecimal digits representing the character's ASCII value.

Why is URL encoding necessary?

URLs can only contain characters from the standard US-ASCII character set. Characters outside this set (like spaces, emojis, or symbols) or characters with special meanings in URLs (like &, ?, =), must be encoded so they do not break web routing.

What is the difference between encodeURI and encodeURIComponent?

In JavaScript, `encodeURI` is used to encode a full URL without changing valid URL characters like /, ?, :, and &. `encodeURIComponent` is designed to encode a specific query parameter value, encoding even those structural characters.

Is URL encoding secure?

No. URL encoding is purely for formatting web-safe links and data packets. It is easily decodable and provides absolutely no security or data encryption.
