URL Encoder
About the URL Encoder
A URL Encoder ensures your URLs are clean, secure, and web-friendly by transforming special characters into a universally accepted format. This process, known as percent encoding, replaces unsafe characters with a % followed by a unique hexadecimal code, preserving the integrity of your links and ensuring seamless transmission across the internet.
URLs can only safely contain a limited set of characters — letters, digits, and a handful of symbols like -, _, ., and ~. Anything else, including spaces and reserved characters like &, ?, and =, has to be encoded so it isn't confused with the URL's own structure. Whether you're sharing links, handling web data, or optimizing SEO, encoding guarantees your URLs remain error-free and fully functional in any browser or application.
How to Use the URL Encoder
Enter text or a URL
Paste the text or URL containing characters you want to encode.
Click "Encode"
Special characters are instantly converted to percent-encoded form.
Copy the result
Use the "Copy" button to grab the encoded output.
Common Use Cases
Building Query Strings: Safely encode search terms, filters, or user input before appending them to a URL.
Sharing Links with Special Characters: Encode spaces, accents, or symbols in a link so it survives being pasted into chat apps or emails.
Constructing API Requests: Encode parameters before sending them in a GET request or webhook payload.
Debugging Broken Links: Check whether an unencoded special character is the reason a URL is failing to load correctly.
How Does URL Encoding Work?
URL encoding replaces reserved and unsafe characters with a % followed by their corresponding hexadecimal value. Here are some common examples:
| Character | Encoded Version | Explanation |
|---|---|---|
| Space ( ) | %20 | Spaces are not allowed in URLs |
| Exclamation Mark (!) | %21 | Reserved character in URLs |
| Ampersand (&) | %26 | Used to separate query parameters |
| Question Mark (?) | %3F | Indicates the start of a query string |
| Equal Sign (=) | %3D | Used in key-value pairs in query parameters |
| Plus Sign (+) | %2B | Often confused with space, must be encoded |
