SmartUpscale troch Marat Tanalin

Prevents blurring images which have their size in physical pixels an integer number of times larger than their natural size.

Useful with high-DPI monitors, including 4K/5K monitors at 200% OS-level zoom.

Images are processed once the page is fully loaded, as well as after dynamic changes on the page and on changing browser-level zoom.

Extension’s options allow to limit maximum image zoom that blur should be prevented at, and to disable blur globally if needed.
