URL Encoder and Decoder

URLs can contain characters that have a special meaning on the internet. Characters such as spaces, symbols and non-ASCII characters may need to be encoded before they can safely be included in a URL.

A URL encoder converts these characters into a format that can be safely transmitted as part of a web address.

What is URL encoding?

URL encoding, also known as percent-encoding, replaces certain characters with a percent sign followed by hexadecimal values.

For example, a space is commonly represented as %20 .

Why is URL encoding needed?

URLs have a defined syntax and some characters have special purposes. Encoding allows characters that could otherwise interfere with that syntax to be represented safely.

URL encoding is commonly used when working with query parameters, APIs, redirects and web applications.
