2 · Design base size
The scale your uploaded files were designed at. Everything smaller is downscaled from it; buckets above it are skipped, so nothing is ever upscaled.

Output sizes
base 4x8 per image
Add images to see every size you'll get
Sizes are computed from each file at your 4x base scale — for example a 1024×1024 source becomes:
@1x 256×256@2x 512×512@3x 768×768mdpi 256×256hdpi 384×384xhdpi 512×512xxhdpi 768×768xxxhdpi 1024×1024
Where these folders go
- 1
ios/— drop each file into its image set in Assets.xcassets; @2x/@3x land in the right slots. - 2
android/drawable-*— merge into your module's res/ folder; every density keeps the same file name.
AppListingLab
Building the whole app listing?
Scaling assets is the easy half. The Studio creates the listing itself — store screenshots and ASO copy from one shared app profile, so everything stays on message.
- Story-driven screenshot sets for every device size
- App Store & Google Play copy within each store's limits
- Both stores and every language you sell in
- One app profile behind all of it
