URL decoding reverses the percent-encoding process. It converts sequences like %20 back to a space, %2F back to a forward slash, and %C3%A9 back to the Unicode character e with an accent. This tool uses the browser's native decodeURIComponent function, which correctly reconstructs Unicode characters from their multi-byte UTF-8 percent-encoded sequences.

About URL Decoding

Percent-encoded URLs are common when working with web APIs, browser address bars, and server logs. A URL like q=hello%20world%26lang%3Den is much harder to read than q=hello world&lang=en. This decoder converts those sequences back to human-readable form so you can debug requests, inspect redirects, or read log entries without doing the conversion in your head. It uses the browser's native decodeURIComponent which correctly handles multi-byte Unicode sequences encoded in UTF-8.
