I recently worked on a project that was getting a ton of traffic but users were bouncing because the page load was too long at around 10 seconds. They called me in because the majority of the images on that site were SVGs, and they were animated. I trained the team how to decrease the file size on the SVGs while preserving the appearance and functionality, finally getting the load time to under 2 seconds. The bounce rate dropped dramatically and conversion was restored.
Some handy tips on optimising SVGs for performance. I’ve been trusting Inkscape for my SVG production needs, but after reading this, I might take a closer look at the files it creates.
