URL Encoder/Decoder
Encode or decode URLs and query parameters. All processing happens locally.
What is URL Encoding?
URL encoding (also called percent encoding) converts characters into a format that can be safely transmitted over the internet. Special characters like spaces, ampersands, and question marks are converted to %XX format where XX is the hexadecimal value.
This tool supports both encodeURI (for full URLs) and encodeURIComponent (for individual parameters). Use encodeURI when encoding a complete URL, and encodeURIComponent when encoding query string values or path segments.
Common Use Cases
Encoding query parameters with special characters, building URLs dynamically in JavaScript, debugging URL encoding issues, safely passing data in URLs, and encoding spaces and special characters in API requests.
