URL encoding is essential when passing data in APIs, query parameters, forms, or web applications, because browsers cannot process certain characters directly. This free tool allows you to handle encoding and decoding instantly without errors.
URL encoding replaces unsafe characters such as spaces, symbols, and Unicode characters with percent-based codes (%20, %3A, %2F), ensuring the link works properly across all browsers and servers. With this tool, both encoding and decoding are done instantly in a clean, user-friendly interface.
