About URL Encoder & Decoder — Percent Encode URLs Online Free

WeLuvTools URL Encoder & Decoder converts special characters in URLs and query strings to their percent-encoded equivalents (e.g. space → %20, & → %26) and decodes them back to readable text. URL encoding ensures that data transmitted in URLs is not misinterpreted by web servers or browsers. WeLuvTools supports both encodeURIComponent (for individual query parameter values) and encodeURI (for full URLs). Everything runs in your browser — your URLs stay private.
