About

URL Decode Online is a free, no-registration web tool for decoding and encoding URLs that works the moment you open the page. It instantly decodes percent-encoded URLs with full UTF-8 support, including multilingual characters and emoji. A built-in multi-layer decoding engine automatically unwraps repeatedly encoded links (such as double-encoded %2520), while error detection highlights malformed escape sequences so developers can pinpoint URL issues in seconds. Beyond decoding, the site offers a matching URL encoder, a URL parser that breaks a link into protocol, host, port, path, query parameters, and hash in one click, and a Base64 decoder. All tools run entirely in your browser — nothing is uploaded to any server — making it safe for sensitive links and internal API addresses. The interface supports 12 languages and a technical blog covers URL encoding fundamentals. Perfect for developers debugging REST API callbacks, QA engineers verifying parameters, and SEO or marketing professionals inspecting UTM links. Free, fast, unlimited, and private: your daily URL debugging toolkit.
