However, we support these for the users that will upload SVC files in their installations in various elements (Icon, Icon Box, Counter). How can you upload a SVG file? All you need is to install and activate a plugin for this (eg https://wordpress.org/plugins/safe-svg/).
Last but not least, a nice place that you can download for free and use the SVG files is here http://linea.io/ (under the folder SVG).
Themes must not enable SVG uploads as it raises security concerns due to the possibility of attackers executing malicious code through SVG’s XML. For more information on SVG uploads, refer to SVG uploads in WordPress article.
