General Photos and Web Images
For standard website photos, blog images, and product thumbnails, lossy compression is ideal because it drastically reduces file size with virtually no noticeable drop in visual quality.
Recommended Quality
80–85This is the sweet spot. The human eye can barely distinguish it from the original, while file sizes are often significantly smaller than JPEG.
Hero / High-Impact Images
85–90Best for large main banners or high-resolution photos where fine detail is critical. Going above 90 can increase file size quickly with only small visual improvements.
General Thumbnails / Speed Optimization
75A solid choice for mobile environments or smaller images where page-load speed is the top priority.
