I found a high-quality website with free svg icons for social networks https://simpleicons.org /. You can download any desired icon in svg or pdf format. You can also install them on the website via composer.

Composer is a package dependency manager designed to simplify downloading and installing third–party php libraries into a project. For example, using it, it is very easy to add php packages to a project under development, as well as deploy other projects that are distributed along with the «composer.json» file.

Most importantly, the icons are already distributed by color, which is attached to each icon and corresponds to the social network.

This site will help web developers well!!!
