What is URL Encoding?
URL encoding (also known as percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). It converts special characters into a safe format that can be transmitted over the internet.
- Spaces become %20 or +
- Special characters like <, >, & are converted to %XX format
- Essential for form data, query parameters, and safe URL transmission
- All processing happens locally in your browser - your data never leaves
