I've been trying to do some work and when i finally finished and went to export my image as a png i get the error message "the operation can not complete because of an unknown error [!now]" I can export as a jpg fine, this is only when i try to export as a png which is the file i mostly use.
Which system, which version?
What's in the file?
How large is the file?
How do you export and exactly where?
Which options when exporting?
I have a mac computer os sierra version 10.12.6
adobe illustrator cc 2018 22.1 i believe
image size 7632x6480 pixels
trying to export to a local folder on my system
File-Expot as- png-hi resolution, art optimized, transparent background
I tried significantly reducing the image size and it saved, thank you!
It may be the complexity of your file but I don't have a proble exporting that size to PNG (Export for Screens or Export As...)
Try from file> export> save for web, then choose PNG 24.
