Frequently Asked Questions
What is URL encoding?
URL encoding (percent-encoding) replaces unsafe characters in URLs with a '%' followed by their hex value. For example, a space becomes %20. This ensures URLs are valid and can be transmitted correctly.
What characters need to be URL encoded?
Characters like spaces, &, =, ?, #, +, and non-ASCII characters must be encoded in URLs. Reserved characters have special meanings in URLs and need encoding when used as data.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL but preserves valid URL characters like :, /, ?. encodeURIComponent encodes everything except letters, digits, and - _ . ~, making it suitable for encoding individual parameters.
