JPG Resize for Web Performance
Serving correctly-sized JPG images is one of the most impactful web performance optimizations. Sending a 4000px photo to a device that displays it at 800px wastes bandwidth and slows your site. Google Lighthouse and PageSpeed Insights specifically flag "properly size images" as an optimization opportunity.

Frequently Asked Questions
