How can I upload an icon for my app on facebook with out the black grainy borders?

I have a logo and when I upload it to facebook it has a black border around it. I think this is because it has a transparent background and has a shad开发者_运维百科ow. Is there anyway to fix this?

Facebook doesn't support transparent images and coverts everything to a JPG file. Save your file as a JPG (using an appropriate background color) and then try to upload it.

This works perfectly, but it will apply a near all white background to your icon.

In Sketch:

1. Add a white (#ffffff) background filled layer to your design
2. Set the Height and Width of the layer to 1023.5
3. Position the layer on the X and Y at 0.5

This will bypass facebook's transparency limitation, and the space around the image is so small you can't see the border that facebook applies to the image.
