Loading Time Optimization and JPEG2000 Image Files

Hi all, I've done a speed test with google for my website and it's warning me that I'm not using JPEG2000 to reduce load time.

I tried changing my images on my website to JPEG2000 but squarespace isn't allowing  me to add that file format to the images function.

Any idea how to resolve this?

My website is www.triggersanj.com

Thank you. 

Squarespace doesn't use the modern photo compression formats. Also, you're using PageSpeed Insights which is designed to test "from the ground up" style websites and not for pre-built template ones. It gives back erroneous info. 

Use https://tools.pingdom.com/ instead to test.

Does Google not rank sites using the PageSpeed data? Mine scores 2/100. Pingdom is 85/100.
