100KB is the practical target most web performance experts recommend for above-the-fold images. At this size, photos look excellent at typical blog widths (800-1200px), product listings stay snappy, and Lighthouse scores stay high.
ImageMint's Target Size tool finds the right quality slider position automatically. WebP often hits 100KB at quality 75-80 for a 1200px-wide photo, while JPEG usually needs quality 70-75 for the same target.
