When uploading your app icon in the Publish Step, you may receive the error message below:
app icon is too heavy
This indicates that the file size is too large.
In this article, you will learn how to fix this error and downsize the app icon in Photoshop.
- Open the app icon in Photoshop.
From the File menu, select Save for Web.
- At the top right, you will see a drop-down with PNG-24. Change this to PNG-8.
