Compress JPEG to 100KB for WordPress Blogs and Shopify Stores

The 100KB sweet spot for US bloggers

For WordPress featured images, Shopify product photos, and Substack newsletters, 100KB is the ideal balance between visual quality and page-load speed. Google PageSpeed Insights and Core Web Vitals reward US sites that keep images under 100KB — meaning higher rankings, more organic traffic, and better conversion rates for your business.

Why US site owners choose 100KB

The average American visitor expects pages to load in under 2 seconds. Compressing your hero images and product photos to 100KB cuts page weight dramatically while preserving the crisp visual quality your customers expect on Retina MacBooks, iPhones, and 4K monitors.
