Encode URLs into a web-safe format or decode percent-encoded URLs instantly online using this free browser-based tool.
URL encoding, also known as percent encoding, converts unsafe characters into a format that browsers and servers can safely transmit over the internet. Special characters such as spaces, symbols, emojis, and non-English text are replaced with encoded values beginning with the % symbol.
URL encoding is commonly used in query parameters, API requests, redirects, authentication flows, and web forms to ensure URLs work correctly across browsers and servers.
