Frequently Asked Questions
What is URL encoding?
URL encoding (percent encoding) replaces special characters with a % followed by their hex code. For example, a space becomes %20. This ensures URLs only contain valid ASCII characters.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL and leaves characters like / and ? intact. encodeURIComponent encodes a URL component and also encodes those characters. Use encodeURIComponent for query string values.
