What is URL Encoding?
URL encoding (also known as percent-encoding) is a mechanism for encoding special characters in URLs. URLs can only contain a limited set of characters from the ASCII character set. Characters outside this set, or reserved characters with special meanings, must be encoded using a percent sign (%) followed by two hexadecimal digits.
encodeURIComponent vs encodeURI
- encodeURIComponent: Encodes all special characters including reserved URL characters like
/ ? # &. Best for encoding query parameter values or path segments. - encodeURI: Preserves URL structure by not encoding reserved characters. Best for encoding complete URLs while maintaining their structure.
Common Use Cases
- Encoding user input for use in query strings or form submissions
- Decoding URLs received from external sources
- Building dynamic URLs with special characters in parameters
- Debugging URL-related issues in web applications
Security Note
All encoding and decoding operations are performed entirely in your browser. Your data is never sent to any server, ensuring complete privacy.
Features
Our URL Encoder/Decoder tool provides a seamless experience for web developers and content creators. Easily convert special characters to percent-encoded format for use in URLs, or decode encoded URLs back to human-readable text.
Choose between full URL mode (preserves URL structure like protocol and slashes) or component mode (encodes everything except alphanumeric characters). Parse URLs into their individual components or build URLs from scratch. All processing happens in your browser - your data never leaves your device.
