Image Megapixel Calculator
Convert image width and height in pixels into a megapixel count.
How to use Image Megapixel Calculator
1. Enter Pixel Width, Pixel Height. 2. Use the oriented image dimensions. Megapixels are an area count and do not measure compression, sharpness or display size. 3. Select Calculate or press Enter. 4. Select Copy result to copy the answer, or Reset to clear the form and result.
Why use this tool?
Use the oriented image dimensions. Megapixels are an area count and do not measure compression, sharpness or display size.
How the calculation works
Megapixels = whole pixel width × height ÷ 1,000,000. Use the oriented image dimensions. Megapixels are an area count and do not measure compression, sharpness or display size. Counts and dimensions use the declared rounding convention; other numbers display up to three decimal places where applicable. Nonzero subsecond durations are labelled. Durations round to the nearest second; nonzero subsecond durations are labelled. File-size output units are decimal. Changing an input label does not convert filled values.
Example
Worked example: Pixel Width = 4000; Pixel Height = 3000. Result: 12 MP.
Practical tip
Check the input labels and assumptions against the image megapixel task before reusing the number.
