What is URL encoding?

URL encoding (also called percent-encoding) converts special characters into a format that can be transmitted over the internet. It replaces characters with a '%' followed by two hexadecimal digits.

When should I use URL encoding?

Use URL encoding when passing special characters (spaces, ampersands, equals signs, etc.) in URL parameters, query strings, or form submissions. It ensures the URL remains valid and properly interpreted.

What's the difference between encodeURI and encodeURIComponent?

encodeURI encodes only characters that are not allowed in URLs (like spaces, special chars) but preserves URI structure. encodeURIComponent encodes ALL special characters including reserved characters like / ? & =, useful for query parameter values.

Does this tool encode the entire URL or just the query parameters?

This tool encodes the entire input. If you need to encode only query parameters, be careful not to encode the URL structure characters like : // ? & = that are needed for the URL format.

Is URL encoding reversible?

Yes! Encoding and decoding are inverse operations. You can decode any percent-encoded string back to its original form using the Decode function.
