Lens: Optimize Images for Lightening Fast Load Times
Oversized files, poorly served formats, and unoptimized media are among the biggest performance killers on the modern web — and most teams don’t even realize it. 75% of sites we test have oversized images. We built LENS to fix that.
WHY IMages are a problem
MANUAL WORK
Manually resizing and re-serving images is tedious, error-prone, and rarely kept up to date.
SLOWWW
Just a 1-second delay in page load time can reduce conversions by up to 20%.
UNNECESSARY WASTE
Images make up 50–70% of a typical webpage’s weight — more than scripts, fonts, or styles combined.
