Free Online URL Encoder / Decoder Tool

Welcome to our powerful online URL encoder / decoder, your go-to utility for handling special characters in web addresses. This free tool allows you to instantly encode URL strings for safe web transmission and decode URL strings back to their original, readable format. Whether you’re a web developer, SEO specialist, or just need to manage complex URLs, our URL converter simplifies the process of URL encoding and URL decoding.

Why You Need a URL Encoder/Decoder

URLs (Uniform Resource Locators) are designed to contain only a specific set of characters. When a URL includes characters outside this safe set—such as spaces, symbols (&, #, ?, /), or international characters (non-ASCII)—they must be converted into a web-safe format. This process is called URL encoding, also known as percent-encoding. Without proper encoding, these characters can break a URL, lead to incorrect server requests, or even pose security risks.

Conversely, when you encounter an encoded URL, you need to decode URL parameters or paths to understand their true content. Our URL string utility makes both operations seamless.

Understanding URL Encoding (Percent-Encoding)

Percent-encoding replaces unsafe ASCII characters with a percent sign (%) followed by two hexadecimal digits representing the character’s ASCII value. For instance, a space becomes %20, and an ampersand (&) becomes %26. This ensures all parts of the URL are valid and correctly interpreted by web servers and browsers. This URL character conversion is fundamental for creating web safe URLs and robust web applications.

encodeURI() vs. encodeURIComponent()

Our tool offers the choice between two crucial JavaScript functions: encodeURI() and encodeURIComponent(). Understanding their differences is vital for correct URL parameter encoding:

  • encodeURI(): This function is used to encode URI components that are part of an entire URL. It encodes characters that are not part of a standard URL syntax (like spaces, |, [). It does not encode characters that are considered special within a URL structure (like &, =, /, ?) because those characters have specific meanings within the URL. Use this for a full URL string.
  • encodeURIComponent(): This is typically the more commonly used function for encoding parts of a URL, such as query string parameters or path segments. It encodes almost all characters that are not letters, digits, or - _ . ~. This includes the special characters &, =, /, ?, which are often found in query strings. Use this for specific data that will be inserted into a URL.

Our URL online converter gives you the flexibility to choose the right encoding method for your specific needs.
