What is URL Encoding?
URL encoding (also known as percent-encoding) converts characters into a format that can be transmitted over the Internet. Special characters are replaced with a "%" followed by two hexadecimal digits.
Why URL Encoding is Needed
- Special Characters: Characters like spaces, &, #, and others have special meaning in URLs
- Data Transmission: URLs can only be sent over the Internet using ASCII characters
- Query Strings: Query parameters must be properly encoded to avoid errors
- Form Data: Form submissions use URL encoding for data transfer
encodeURI vs encodeURIComponent
- encodeURI(): Encodes full URLs but keeps special URL characters intact (/, :, #, etc.)
- encodeURIComponent(): Encodes all special characters including /, :, &, = - used for query parameters
Common URL Encoded Characters
- Space → %20 or +
- ! → %21
- # → %23
- $ → %24
- & → %26
- = → %3D
- ? → %3F
- @ → %40
