How to differentiate 24 Bit PNG and 32 Bit PNG file?


Question

When image is encoded in PNG format, it can be encoded either in 24 bit format (rgb) or in 32 bit format (argb). Both the files appear as .png files. Then how it is possible to differentiate these two types of png files?

To make it more clear, If I am downloading PNG image files from internet how can check in which format it is encoded.

I know this question was asked over a year ago but I stumbled on this post while searching for the answer myself. I found the answer on a different site so I thought I'd share it here.

You can find this information under the Details tab in File Properties. So far it seems to work for files that are natively identified by Windows as an image.

Identify bit depth for image files on Windows:

*Right click* image file > Properties > Details > Bit depth
