Easily encode or decode your URLs for safe data transmission. Convert reserved characters to percent-encoded format or transform complex query strings back into human-readable text — all processed locally in your browser for maximum privacy.
URLs can only be sent over the Internet using the ASCII character-set. Since URLs often contain characters outside the ASCII set, they must be converted into a valid ASCII format. URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. Our tool helps you handle these conversions effortlessly for APIs, web development, and SEO.
Like all Utilexa tools, the URL Encoder/Decoder operates entirely within your web browser. Your input data is never sent to our servers, ensuring that sensitive information, API keys, or private links remain completely confidential.
Whether you are working with UTM parameters, fixing broken links, or debugging server requests, our tool provides instant results. It handles special symbols like ampersands, spaces, and non-Latin characters, making it an essential utility for developers and digital marketers alike.

URL encoding is a mechanism for encoding information in a Uniform Resource Identifier (URI). It involves replacing reserved characters with a percent sign and their corresponding hex value.
You should decode a URL when you have a link that contains percent-encoded characters (like %20 for spaces) and you want to read the original text or parameters clearly.
Our tool can handle very large strings, but keep in mind that most modern browsers and servers have their own URL length limits (usually around 2,048 to 8,192 characters).
No. The encoding and decoding process is done via JavaScript in your browser. No data is transmitted to our servers or stored in any database.
