Image sizes

[Hosun]

Hi,

In Ps, there is Image Size 7.59M.

In Finder, PNG image 660 KB. 

What's the difference between the two image sizes?

Photoshop shows you the uncompressed size according to pixel dimensions and bit depth.

The Finder shows you the compressed size on disk.

The image contains solid colors only, which compress well with the PNG format.
