Frequently Asked Questions

What is URL encoding?

URL encoding converts characters into a format that can be transmitted over the internet. Special characters are replaced with a % followed by two hexadecimal digits representing the character's ASCII code.

Which characters need to be encoded?

Characters like spaces, &, =, ?, #, and non-ASCII characters need to be encoded. For example, a space becomes %20, and & becomes %26.

When should I use URL encoding?

Use URL encoding when passing data in query parameters, form submissions, or any time you need to include special characters in a URL. It ensures data is transmitted correctly.

What's the difference between encodeURI and encodeURIComponent?

This tool uses encodeURIComponent, which encodes all special characters except alphanumeric and -_.!~*'(). It's safer for encoding individual URL components like query parameters.

Can I encode entire URLs?

Yes, but be aware that this tool encodes everything including :, /, ?, and &. For encoding only the parameter values in a URL, encode each parameter separately.
