Image Info: Dimensions and Details
Check an image before you upload or print it: its exact pixel size, file size, aspect ratio, megapixels and whether it has transparency.

- 1Choose an image.
- 2Read its details.
- 3Copy any value you need.
Aspect ratio
Shown as a whole-number ratio, like 3:2 or 16:9, and as a decimal, so you can match the size a site asks for.
Print size
At 300 dpi, the usual print quality, an image's pixels tell you how large it prints sharply, in centimeters and inches.
Transparency and color
You see whether any pixels are transparent, and the image's average color, handy for matching backgrounds.
