URL Encode and Decode converts URLs, query parameters, and text strings into a safe percent-encoded format and back to readable text. URL encoding replaces spaces, Cyrillic characters, emoji, and reserved symbols with sequences such as %20, %2F, %3A, or %D0 so values can be safely used inside links and query strings.
The tool is useful for APIs, UTM tags, redirects, webhook links, tracking URLs, callback URLs, and manual debugging of query parameters. You can encode a full value before inserting it into a URL or decode an already encoded link to understand what it contains.
Processing runs locally in your browser. Entered links and parameters are not sent to the UtiLab server.
