Make your links browser-safe. Use our URL encoder decoder online to transform special characters into %XX formats or clean up messy tracking strings instantly.
AI Overview
URL Encoding (Percent-Encoding) is used to convert unsafe characters in a URL (like spaces or symbols) into a format that web servers can understand. For example, a space becomes %20. This process is essential for ensuring that query parameters, UTM codes, and deep links work correctly across all browsers.
The Domain Name System (DNS) and HTTP protocol can only handle a specific set of characters (A-Z, 0-9, and a few symbols). If a URL contains a space, a slash used as data, or non-English letters, it must be percent-encoded. Our url encoder decoder online tool ensures your links follow the RFC 3986 standard.
Developer Tip: Use "Double Decode" if you encounter URLs where the % symbol itself has been encoded (like %2520). This is common in security forensics and when investigating malicious phishing links.
