Why I can't PNG download?
 

When I try to download a picture in PNG format, an error occurs. How do I download a PNG format? The GIF format in some figures is too sharp pixels and it takes them a long time to fix them.

Error:

"There was an error, please try again
- File upload error (field: 1:1 Scale GIF)"

1:1 images MUST be a GIF file...

Please transform PNG into GIF first, and then upload your drawing.
