Boxy SVG is a desktop app which works across all computer types (Mac, PC, Linux, Chrome OS) and which allows you to easily edit any .SVG vector file without needing to download, purchase or install any software.
*This is an offline desktop app that DOES NOT track you and DOES NOT send any your data to remote servers.
