Is it possible to use .png images for WiX bitmaps

Question

I am using 2 500K bitmaps in to display images on my WiX dialogs.

They dramatically increase the size of the installation package, and what is worse - it looks there

Answer 1

Yes, if you only need to install on Windows 8 or later. From Bitmap Control:

Windows 8 and Windows Server 2012: The image file can be in any standard format supported by the Windows Imaging Component (WIC), including TIFF, JPEG, PNG, GIF, BMP, and HDPhoto. The control does not support animation.
