Without knowing anything about your document and its settings, nobody can tel lyou much. You could simply be in a wrong color mode or something like that. Other than that this could be one of those endless PNG-related bugs in recent versions of ADobe products. Something is seriously broken....
What version of photoshop do you have?
If your using CC 2018 (photoshop version 19.0) have you updated to 2018.0.1 (19.0.1)?
Look under Help>System Info and first line to show the photoshop version.
How to tell if you have 19.0.1
Help>Updates from within photoshop.
Thanks, but updating did not solve this issue. I just upgraded to
Adobe Photoshop Version: 19.0 20171103.r.190 2017/11/03: 1143799 x64
Adobe Photoshop Version: 19.0 20170929.r.165 2017/09/29: 1138933 x64
Maybe I should go back and try an older version.
Reset the photoshop preferences and see if that makes a difference.
Go to Edit>Preferences>General, click on Reset Preferences On Quit and restart photoshop.
That did not help.
I just went back to version 18 (2017), and it works great! I can now export PNG files perfectly! I'll just stick with this version.
It might be a bug or something.
I did notice that adobe seems to have removed the png plugin from the Standard MultiPlugin and it's no longer listed in the Help>System Info, so i guess it's now integrated into photoshop instead of a separate plugin like quite a few other file formats are, though that's strange that png is the only file format missing from Save As when compared to the cc 2018 here on my own windows 10 install.
Not be able to Export as a PNG Sequence is a confirmed bug, so i wonder if the Save As png is related to that?
Thanks. I think the Save As thing only disappears when you turn on timeline.
I have the save issue, and I used "File>Export>Export As..." as a workaround.
