URL Encoder/Decoder

About URL Encoding

URL encoding, also known as percent-encoding, is a method to encode special characters in a URL to ensure safe transmission of data over the Internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.

How URL Encoding Works

URL encoding follows these rules:

• Alphanumeric characters (A-Z, a-z, 0-9) remain unchanged
• Special characters are converted to their ASCII hex value, prefixed with %
• Spaces can be encoded as either + or %20
• Line breaks are encoded as %0A or %0D or both

Common Use Cases

• Encoding query parameters in URLs
• Handling special characters in API requests
• Processing form data submissions
• Creating valid URLs from strings with spaces or special characters
• Debugging URL-related issues in web applications

When to Use URL Encoding

URL encoding is necessary when:

• Adding query parameters to URLs that contain special characters
• Ensuring URLs remain valid when they contain spaces or unicode characters
• Passing data through URLs in a web application
• Working with APIs that require encoded parameters
• Handling user input that will be part of a URL

Best Practices

• Always encode user input before adding it to URLs
• Use the appropriate encoding function for your context (encodeURI vs encodeURIComponent)
• Be aware that some characters have special meaning in URLs
• Test URLs with both encoded and decoded values
• Consider double-encoding issues when working with multiple systems
