How do you convert dpi to byte?

DPI (dots per inch) is a measure of print resolution and does not directly convert to bytes, as it describes the density of dots in a printed image rather than data size. To estimate the file size in bytes, you need to know the image's dimensions (in inches), color depth (bits per pixel), and the intended DPI. The formula for calculating the approximate file size in bytes is: width (in inches) × height (in inches) × DPI² × (color depth/8).
