The Online URL Encoder Tool is a simple utility that allows users to encode URLs or strings so that they can be safely embedded in web pages and URL queries.

Overview

The Online URL Encoder Tool is a simple utility that allows users to encode URLs or strings so that they can be safely embedded in web pages and URL queries. URL encoding replaces non-ASCII characters and some special characters with a “%” followed by two hexadecimal digits representing the character’s ASCII code.

How to Use

1. Open the provided HTML file in a web browser.

2. Enter the URL or string you want to encode in the first text area.

3. Click the “Encode” button to perform the encoding.

4. The encoded URL will appear in the second text area.

5. You can use the “Reset” button to clear both text areas or the “Copy” button to copy the encoded URL to the clipboard.

Sample Data for Testing

Sample URL: https://www.example.com/search?q=openai gpt-3

Encoded Result: https%3A%2F%2Fwww.example.com%2Fsearch%3Fq%3Dopenai%20gpt-3

Sample String with Special Characters: Hello, World! This is a test.

Encoded Result: Hello%2C%20World%21%20This%20is%20a%20test.

String with Non-ASCII Characters: München, Germany

Encoded Result: M%C3%BCnchen%2C%20Germany

To test, simply input the sample data into the text area and observe the encoded result.

URL Encoding with JavaScript

JavaScript provides the built-in encodeURIComponent function to perform URL encoding.

var url = "Hello World!";
var encodedUrl = encodeURIComponent(url);
console.log(encodedUrl); // Outputs: Hello%20World%21

URL Encoding with Java

In Java, you can use the URLEncoder class provided by the java.net package to perform URL encoding.

import java.io.UnsupportedEncodingException; 
import java.net.URLEncoder; 

public class UrlEncoderExample { 
    public static void main(String[] args) { 
        try { 
            String url = "Hello World!"; 
            String encodedUrl = URLEncoder.encode(url, "UTF-8"); 
            System.out.println(encodedUrl); // Outputs: Hello+World%21 
        } catch (UnsupportedEncodingException e) { 
            throw new RuntimeException("UTF-8 encoding is not supported", e); 
        } 
    } 
}

Conclusion

The Online URL Encoder tool is a straightforward utility for encoding URLs and strings. This documentation provides a brief overview, instructions for use, an overview of the code, and sample data for testing.
