Perceptible Quality Loss of JPG/JPEG Compression
At what JPG/JPEG compression level should I see perceptible quality losses?
✍: FYIcenter.com
In general, quality levels of 90% or higher are considered "high quality". At 90%, there is very little difference in smooth areas. But edges of objects are not as crisp as the original picture.
Quality level of 80% to 90% is "medium quality". At 80%, picture details are a little blurry.
Quality level of 70% to 80% is "low quality". At 70%, edges objects are no longer crisp and compression artifacts are visible.
Quality level of 70% and lower is "poor quality". At 50%, significant quality losses are visible around all edges.
