Frequently asked questions
Multiply width by height by bits per pixel, divide by 8 for bytes. A 1920×1080 24-bit image is about 5.93 MB uncompressed.
It is the colour depth: 24-bit is standard RGB, 32-bit adds transparency, 8-bit is greyscale or indexed.
Formats like JPEG and PNG compress the data, so saved files are usually much smaller than the raw size.
This uses 1,048,576 bytes (1024 × 1024) per MB, the binary convention.
