Frequently Asked Questions

Everything you need to know about app store screenshot requirements.

What are the required iPhone sizes for 2026?

Apple currently requires 6.9" (iPhone 16 Pro Max - 1320x2868) or 6.7" (1290x2796) and 6.5" (1242x2688) for all iPhone apps. iPad apps require 13" or 12.9" device screenshots.

Does this tool support Google Play flexible sizes?

Yes. Google Play allows screenshots between 320px and 3840px with an aspect ratio of 2:1 or 1:2. Our tool validates these specific ranges automatically.

Will resizing reduce my image quality?

We use high-quality sampling algorithms on the canvas to ensure text remains crisp and colors stay vibrant during the upscaling or downscaling process.

Is there any cost or watermarks?

No. This is a free utility provided by ASO Studio to help developers. All exports are high-resolution PNGs with absolutely no watermarks.
