About URL Encoder / Decoder
Last updated: May 2026
OptiPix URL Encoder/Decoder converts text between human-readable and percent-encoded URL formats. Use encodeURIComponent (default), encodeURI, or full percent-encoding modes. Toggle live mode to auto-convert as you type. The built-in URL parser breaks any URL into its components - protocol, host, port, path, query parameters, and fragment - making it easy to inspect and debug URLs. Copy encoded or decoded text with one click. Perfect for web developers working with query strings, API integrations, and URL debugging. Everything runs in your browser - no data is sent to any server.
How It Works
The tool uses JavaScript's built-in encodeURIComponent(), encodeURI(), and decodeURIComponent() functions for standard encoding/decoding. The URL parser uses the URL constructor to decompose URLs into their RFC 3986 components.
Use Cases
- •Encode query parameters for API requests
- •Decode percent-encoded URLs for debugging
- •Parse complex URLs to inspect individual components
- •Prepare text for safe inclusion in URL paths
- •Debug URL query strings with special characters
