Can't place TIF or PNG files into InDesign. The internet tells me that I can, however I've been trying for hours and it only works when I convert to JPG.
It is possible to place TIF/PNG files in InDesign. No need to convert to JPG. We’ve tried this and it works for us.
To see why it is not working for you, could you share a sample TIF/PNG file with us (email@example.com)?
