URL Encoder / Decoder

URLs often include characters that need encoding before they can be safely transmitted in query strings or API calls. This URL encoder converts spaces, symbols, and non-ASCII characters into percent-encoded sequences so you can embed data without breaking a request. The decoder performs the reverse operation and returns a clean, readable string, which is essential when you are debugging redirects, analytics links, or server logs.

The tool supports full URI encoding and decoding with instant results. Use it to prepare search queries, build deep links for mobile apps, or decode complex callback URLs during authentication flows. Because the utility runs entirely in the browser, you can handle sensitive parameters locally. It is a fast, reliable companion for any workflow that deals with redirects, webhooks, or query serialization. When a URL looks garbled, this tool helps you see the underlying data in seconds.

When you are unsure whether to encode a full URL or just a parameter, this tool makes it easy to experiment. Try encoding a single query value and compare it to encoding the entire link so you can mirror how browsers handle input fields.

Percent encoding is defined by RFC 3986, so reserved characters like ? and & keep their meaning while other symbols are escaped. If you see + for spaces in a query string, this tool will help you confirm the exact encoding your framework expects.
