How the Uncompressed Image Size Calculator works
Size = width × height × bits per pixel ÷ 8. Compressed formats such as JPEG are usually 5 to 20 times smaller. Example: with Width 6,000 px, Height 4,000 px, and Color depth 24-bit (8 per channel), the result is Uncompressed size (MB) = 72; Megapixels = 24; Size in MiB = 68.7.
