For App Store sellers
Screenshot resizing for app developers
Drop your product photos, pick the App Store preset, and get back a ZIP sized to App Store's own rules. No account for the free pack, and your photos never leave your browser.
Why this is slower than it should be
- ·Apple accepts only certain screenshot sizes for each device class, and Google Play sets limits of its own, so one set of screenshots rarely fits both stores as it is.
- ·App Store screenshots must be JPEG or PNG without transparency, and a screenshot with a different shape loses its edges if it is cropped to fill.
- ·Every new device size or store requirement means redoing the whole set of screenshots by hand.

Questions
What sizes does the App Store accept?
See the full, sourced answer in the App Store screenshot size guide, including the accepted sizes for each device class.
Can SizeSpec do Google Play too?
Yes. The studio has presets for Google Play screenshots and the feature graphic, each with its own sourced guide.
Are my screenshots uploaded to SizeSpec's servers?
No. Resizing happens in your browser; screenshots are never uploaded.
