What is URL encoding?

URL encoding (percent encoding) converts special characters in URLs to a format that can be transmitted over the internet. Special characters are replaced with % followed by their hexadecimal ASCII code.

When should I use URL encoding?

Use URL encoding when URLs contain special characters like spaces, ampersands, or non-ASCII characters. It's essential for query parameters, form data, and ensuring URLs work correctly across all systems.

What characters need to be URL encoded?

Characters that need encoding include spaces, &, ?, #, %, +, =, and non-ASCII characters. Reserved characters like : / ? # [ ] @ and unsafe characters like spaces, quotes, and should be encoded.

Is URL encoding the same as HTML encoding?

No, URL encoding and HTML encoding are different. URL encoding uses % followed by hex codes for web addresses, while HTML encoding uses entities like & for HTML content.
