URL Encoder/Decoder
Encode or decode URL components with percent-encoding for query strings and special characters.
What is URL Encoding?
URL encoding, also known as percent encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI) under certain circumstances. It is used to represent characters that are not allowed in URLs or have special meanings in URLs.
When you need to include special characters, spaces, or non-ASCII characters in a URL, they must be encoded using percent encoding. This ensures that the URL remains valid and can be properly transmitted over the internet.

Frequently Asked Questions
What characters need to be URL encoded?

Should I use encodeURI or encodeURIComponent?
Use encodeURIComponent for query values and individual components; encodeURI is for full URLs where structure characters must stay unencoded.
