What is URL Encoding?

URL encoding converts special characters to a % followed by two hexadecimal digits. This ensures URLs are transmitted correctly over the internet. For example, spaces become %20.

Common Use Cases

• Preparing API request parameters
• Fixing broken links with spaces or special characters
• Encoding form data for submission
• Creating properly formatted URLs
• Handling international characters in URLs

Important Notes

Encode full URLs only when necessary. Typically, you should encode individual query parameters. Some characters like :, /, ?, and # have special meaning in URLs and should not be encoded in the main URL structure.
