Advanced tools
The postcss-normalize-url npm package is a PostCSS plugin designed to normalize URLs within your CSS. This includes operations such as normalization of quotation marks, removal of default ports, and encoding of special characters in URLs. It helps in reducing the size of your CSS by ensuring URLs are optimized and consistent.
Normalization of URLs
This feature normalizes URLs by removing the default port (80 for http and 443 for https) and ensures the URL is encoded properly. It also normalizes quotation marks around URLs.
postcss([ require('postcss-normalize-url')() ]).process('a { background-url: url(http://example.com:80/image.png); }').then(result => { console.log(result.css); });Removal of unnecessary quotes
This feature removes unnecessary quotes around URLs when they are not required, which can help in reducing the size of the CSS file.
postcss([ require('postcss-normalize-url')() ]).process('a { background-url: url("http://example.com/image.png"); }').then(result => { console.log(result.css); });Encoding of special characters in URLs
This feature ensures that special characters in URLs are properly encoded, making the URL safe to use across different browsers and environments.

It includes functionalities for minifying CSS, which indirectly includes optimizing URLs within stylesheets. However, it is more comprehensive in scope, focusing on overall CSS optimization rather than specifically on URL normalization.
