About Image Compression

Image compression reduces file size by removing data — either losslessly (keeping all visual information) or lossily (discarding data that is hard to perceive). JPEG and WebP use lossy compression with adjustable quality levels. A quality of 80% typically provides an excellent visual result at 20-40% of the original JPEG file size. WebP achieves even smaller file sizes at equivalent visual quality compared to JPEG.

Web images are one of the biggest factors in page load performance. Google PageSpeed Insights and Lighthouse consistently flag oversized images as a top optimization opportunity. Serving properly compressed images can reduce page weight by 50-80% and significantly improve Core Web Vitals scores, particularly Largest Contentful Paint (LCP).

FAQ

What quality setting should I use?
For most web images: 75-85% quality provides excellent visual results with significant size reduction. For thumbnails and background images: 60-70%. For hero images and prominent photography: 85-90%. Always compare the original and compressed versions visually — the right setting depends on the image content.
Should I use WebP or JPEG?
WebP produces 25-35% smaller files than JPEG at equivalent quality. All modern browsers (Chrome, Firefox, Safari 14+, Edge) support WebP. For maximum compatibility with older systems or when browser support is unknown, use JPEG. Use the picture element with WebP source and JPEG fallback for the best of both worlds.
