What is URL Encode?
This URL Encode tool converts text and URLs into percent-encoded format, making them safe for use in web addresses, query parameters, and API requests. Special characters like spaces, ampersands, equals signs, and Unicode characters are converted to %XX format (e.g., space becomes %20). This is essential for creating valid URLs, encoding query strings, UTM parameters, and ensuring your links work correctly across all browsers and platforms.
How to Use
1
Paste the text or URL you want to encode
2
Click Encode to convert to percent-encoded format
3
Copy the encoded output for use in your URLs or API calls
