How to export an image from Photoshop CC with dimensions (15300 x 10500) to one PNG without scaling down?
I have multiple images at 15300 x 10500 pixel and created them at this size. However, I can not export it at this ratio to PNG. No matter which way I try "export as ...", "For Web" or "Fast export", I can not put the scaling to 100%. At "Export as ..." maximum is 78%, at "For Web" it is 53,54%. Different images (at the same original pixel dimensions) give the same maximum.
There is a white background and many areas with the same color, so file size is not an issue. The actual file size on the smaller ratios is <2MB.
If i "export layers" the background layer is at its full size, but if I create a merged layer and try to export that single layer it is scaled down, too.
At Illustrator I don't have trouble exporting to full size.
Any help appreciated!
