Frequently Asked Questions

What is URL encoding?

URL encoding (percent-encoding) converts characters that are not allowed in URLs into a format that can be transmitted over the Internet. Each character is replaced by a percent sign followed by its hexadecimal ASCII code.

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a complete URL and does not encode characters like /, ?, &, =, #. encodeURIComponent encodes a URL component (like a query string value) and encodes ALL special characters, making it safe to use as part of a query string.
