URL Encode Online

Safely encode your URLs and query string parameters to ensure they are transmitted correctly over the internet.

Understanding URL Encoding

URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL must be replaced with a '%' followed by two hexadecimal digits.

Query Parameter Safety

Encoding is essential when passing data through URL query strings, ensuring that spaces and special characters don't break the link.

Standard Compliant

Our tool follows standard RFC 3986 guidelines for URI encoding, ensuring compatibility with all modern browsers and servers.

Frequently Asked Questions

Which characters are encoded? Characters like spaces, ?, &, =, and non-ASCII characters are converted to their percent-encoded equivalents.

Is it case-sensitive? Percent encoding itself is not case-sensitive, but URLs can be. Our tool uses standard uppercase hex digits for maximum compatibility.

Why is my space a %20? In URL encoding, the space character is represented as %20. Some contexts also use '+', but %20 is the standard for URIs.
