Why this png image is rejected they say quality issues.

Hi @Waseem35297664szvg ,

The edge of the picture becomes jagged when zoomed.

Best wishes,

Here's what your competition is doing. Floating mobile phone icon generated with AI. 

Unlike yours, this example is a commercial quality (5120 x 3584) JPEG with good design and details. 

As a customer, which one would you buy? 

Also, PNG is for vector graphics or rasters containing transparency. See PNG requirements below.

Hope that helps. 

The edges aren't very smooth and look pixelated.
