What Is URL Encoding?
URL encoding, also known as percent encoding, is the process of converting special characters into a format that can be transmitted safely over the internet. URLs can only contain certain characters. When unsafe characters such as spaces, ampersands, or symbols are included, they must be encoded.
For example:
- Space becomes %20
- & becomes %26
- # becomes %23
Why URL Encoding Is Important
Prevents URL Errors
Improperly formatted URLs can break web pages or APIs. Encoding ensures characters are interpreted correctly.
Ensures Browser Compatibility
Different browsers interpret special characters differently. Encoding guarantees consistency.
Required for Query Parameters
When passing values like names or search terms, encoding prevents query conflicts.
Improves Data Transmission
Encoding protects URL integrity during data exchange between client and server.
