What is URL Encoding?
URL encoding (also known as percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL must be converted to a valid format.
When to use this tool?
- Encoding: When you need to send data in a URL query string. For example, converting a space to
%20or+. - Decoding: When you have a URL with encoded characters and want to see the original text.
How it works
This tool uses JavaScript's built-in encodeURIComponent and decodeURIComponent functions. Since it runs entirely in your browser, your data is never sent to any server, ensuring 100% privacy and security.
