Cannot set app icon with transparency to iTunes Connect [duplicate]

Question

iTunes Connect has been updated in the last few days, now when I try to update App Icon (not screenshot) I get the following error:"Images can't contain alpha channels or transparencies."

I had no such trouble in the past, has Apple changed its guideline on app icon or is this perhaps a bug in the new site? If the guideline has been changed, is the solution to simply remove any transparency?

Answer 1

Here is the cool stuff which will solve this problem.

Step 1 - Open your icon image in Preview Step 2 - Go to File -> Export, You will get a drop-down as shown in the image below. Step 3 - Uncheck the Alpha and Save

Then use the exported icon Image. Now it will work.

Answer 2

• Open your image(1024x1024) with Gimp and go to File --> Export
• Select File Type as JPEG image and click Export button on the right bottom corner.

Answer 3

Your icon should be without transparency(Alpha Channel) and of size 1024 X 1024. It could be either JPEG, JPG or PNG type. Refer apple doc here

I have also attached a screenshot for which highlights the size & other specs for icon.

Answer 4

Remove any transparency from your app icon and try to upload app icon after that... See here
