What is URL Decoder?

URL decoding is the reverse of percent-encoding — it converts %XX escape sequences back into their original characters. When URLs appear in server logs, analytics dashboards, email links, or API responses, they are often percent-encoded and difficult to read. For example, a Google Analytics campaign URL with multiple UTM parameters may look like a wall of %3D and %26 characters. URL decoding reveals the original query string parameters, making it easy to audit tracking links, debug redirect chains, and inspect URL-encoded API payloads. This tool handles both standard percent-encoding (%20 for space) and the + sign as space convention used in HTML form submissions.
