Resolution & Crop Simulator

See how much you can crop or digitally zoom from a source resolution into common delivery formats without falling below the target pixel count.

UHD 4K can be cropped to 2.00× for HD delivery before upscaling begins.

Quality rule

Green means the crop still contains at least the target resolution.

Green: no upscaling. Yellow: mild upscaling up to 1.25×. Red: stronger upscaling and visible quality loss is increasingly likely. This simulator evaluates pixel dimensions only; codec, compression, debayering, lens sharpness and noise can reduce real-world detail before the mathematical limit.
