Why Compress to 80KB?
Mobile-first web design guidelines from Google recommend keeping individual above-the-fold images well under 100KB to maintain fast Largest Contentful Paint (LCP) scores. At 80KB, blog sidebar images, author headshots, and small hero banners load almost instantaneously on 4G connections. Shopify and WooCommerce product-card thumbnails displayed in grid views benefit from this target — the images are large enough to show product detail but small enough to keep collection pages fast. Some Slack workspace custom emoji and status-image uploads also work best at or below 80KB.
Tips for Compressing to 80KB
For blog sidebar images, 80KB at 300px wide is more than sufficient — avoid uploading full-width hero images in sidebar slots.
Run a Lighthouse audit after updating images to verify your LCP improved.
If multiple 80KB images appear on the same page, consider lazy-loading below-the-fold images to further improve performance.
