What is URL encoding?

URL encoding (percent-encoding) converts characters not safe in URLs into a transmittable format. For example, a space becomes %20 and an ampersand becomes %26.

encodeURIComponent vs encodeURI

Use encodeURIComponent for individual query parameter values. Use encodeURI for full URLs. All processing runs locally in your browser.
