Example / Use Case
Encode Query Parameters
A developer needs to add user input as a query parameter in a URL. They encode the input first to ensure special characters dont break the URL.
Input
Text: John Doe&age=30
Output
Encoded: John%20Doe%26age%3D30
How It Works
URL encoding, also known as percent encoding, is required because URLs can only contain a limited set of ASCII characters. All special characters, spaces, and non-ASCII characters must be encoded using the % prefix followed by two hexadecimal digits representing the character byte value.
For example, space becomes %20, exclamation mark becomes %21, and so on. This ensures URLs work correctly across all browsers and servers. The RFC 3986 standard defines the exact characters that need encoding. For decoding URL-encoded strings back to normal text, use the URL Decoder tool.
