JPEG compression works by reducing the amount of colour detail stored in areas of the image where the human eye is less sensitive — gradients, smooth backgrounds, and out-of-focus areas. At 40-60% compression, most photos lose less than 5% visible quality while reducing file size by 60-80%. The difference is practically invisible on screen but makes a significant impact on load times.
The key is finding the right balance for your use case. Web images can tolerate more compression than print. Thumbnails can be compressed more aggressively than hero images. The Web Asset Suite compressor shows you the exact output file size and percentage reduction after compression, so you can adjust the slider until you hit your target.
JPG Compression Settings — What to Use for Each Use Case
Blog & article photos
Use 50-60% compression. Target output: 100-200KB per image. This gives fast load times without any visible quality difference in editorial photography.
E-commerce product photos
Use 40-55% compression. Target output: 100-300KB. Product photos need to remain sharp and detailed — go lower on the slider to preserve texture and sharpness.
Website hero & banner images
Use 50-65% compression. Target output: under 200KB. Hero images are the largest on the page and have the biggest impact on Largest Contentful Paint (LCP) score.
Thumbnails & preview images
Use 65-80% compression. Target output: under 50KB. Thumbnails display at small sizes so higher compression is fine — the quality loss is invisible at thumbnail dimensions.
Why JPG File Size Matters for Website Performance
JPG is the most common image format on the web and typically the largest contributor to page weight. A single uncompressed product photo can be 3-8MB. At 60% compression, that becomes 600KB-1.6MB — still large. At 75% compression, it becomes 300KB-800KB, which is the target range for most web use cases.
Google's Core Web Vitals measure page load performance as a search ranking signal. The Largest Contentful Paint (LCP) metric specifically measures how fast the main image on a page loads. Compressing your JPG images is one of the fastest wins for improving your LCP score and therefore your search rankings.
After compressing your JPGs, you may also want to remove the background from product photos to create clean transparent PNG assets for your store.
