URL encoding (percent-encoding) converts special characters in URLs into safe representations using percent signs followed by hex values. Our free URL Encoder ensures your URLs and query parameters are properly encoded.
Special characters like spaces, ampersands, question marks, and non-ASCII characters must be encoded when used in URLs. Without proper encoding, URLs may break, cause errors, or create security vulnerabilities.
Use this tool when building API queries, constructing redirect URLs, encoding form data, or ensuring URLs with special characters work correctly across all browsers and servers.
