URL Encoder & Decoder
Encode text to URL format and decode URL-encoded strings instantly. Perfect for web development, API integration, and handling special characters in URLs with RFC 3986 compliance.
How URL Encoding Works
- • Converts special characters to %XX format
- • Uses UTF-8 encoding for Unicode characters
- • Safe for HTTP URLs and query parameters
- • Preserves alphanumeric characters and safe symbols
- • RFC 3986 compliant encoding standard
Common Characters
💡 Pro Tips
- • Always encode URLs before sending them in HTTP requests
- • Use encodeURIComponent() for query parameter values
- • Use encodeURI() for complete URLs (preserves :// and /)
- • Our tool uses encodeURIComponent() for maximum compatibility
- • URL encoding is reversible - you can always decode back to original

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 characters into a format that can be transmitted over the Internet safely. Characters are converted to %XX format where XX is the hexadecimal representation of the character.
