Frequently Asked Questions
What is URL encoding?
URL encoding (also called percent-encoding) converts characters that are not allowed in URLs into a '%XX' format where XX is the hexadecimal ASCII code. For example, a space becomes %20.
When do I need to URL encode a string?
Whenever you include special characters in a query parameter, form field, or API path. Characters like spaces, &, =, ?, #, and non-ASCII text must be encoded to form valid URLs.
What's the difference between encodeURI and encodeURIComponent?
encodeURI encodes an entire URL, leaving characters like / and ? intact. encodeURIComponent encodes a single component (like a query value), encoding those characters too. This tool uses full component encoding.
Should I encode the entire URL or just the parameters?
Only encode the individual parameter values, not the full URL. Encoding the entire URL would corrupt the slashes and protocol, making it invalid.
