With 1000s of different physical screen sizes and pixel densities to consider one image can't optimally support them all.
Users on mobile devices have limited bandwidth and battery capacity which is wasted displaying large images. Worst still user experience is degraded as page load time is reduced.
51Degrees image optimiser solves this problem. Consider the image table to the left. The same high resolution source image is used for each cell but it's requested at a different size. Each image is precisely optimised for the available space.
Delight your users with fast images optimised for their precise device.
