Percent-Encoding: The Logic Behind the Tool
URL Encoding, also known as Percent-Encoding, transforms characters that are 'reserved' in a URI (like /, ?, #, and &) into a safer, three-character sequence starting with a percentage sign followed by two hexadecimal digits. For example, a space becomes %20 and an ampersand becomes %26.
This process is vital for Query Parameters. When you are passing a search term or a user-generated comment through a URL, failing to encode characters like '=' can cause the server to misinterpret your keys and values, leading to 400 Bad Request errors or broken application state. Our tool follows the RFC 3986 standard to provide the most reliable encoding possible.
