App store screenshot generator
App store screenshots are the single largest conversion lever on a listing, and both stores enforce exact pixel dimensions for them. This free generator takes raw captures, frames and resizes them to current App Store and Google Play requirements, and applies caption guidance based on what the first three images have to accomplish: state the core benefit, prove it, and remove the main objection. It runs in the browser, so nothing you upload leaves your device.
Start with your current set
Before you rebuild the screenshots, see how the current set scores. appXL reviews your live listing's creative alongside its metadata and tells you which image is losing the install. Free, no signup.

- 1
Upload your captures
Add raw screen captures from a device or simulator. Order them so the strongest benefit is first.
- 2
Choose store and device
Pick App Store or Google Play and the device class, and the correct output dimensions are applied automatically.
- 3
Write the captions
One benefit per image, in the words users use. The caption should make sense with the image muted and cropped.
- 4
Export the set
Download the sized set and upload it in App Store Connect or Play Console.
Current screenshot requirements
| Store | Required set | Count | Notes |
|---|---|---|---|
| App Store | 6.9in and 6.5in iPhone displays | Up to 10 per localization | Other sizes are scaled from the largest supplied set |
| App Store | 13in iPad display | Up to 10 | Required only if the app supports iPad |
| Google Play | Phone screenshots, 16:9 to 9:16 | 2 to 8 | Minimum 320px, maximum 3840px on any side |
| Google Play | Tablet screenshots | Up to 8 | Required for tablet-featured placement |
Store requirements change with each new device generation. Supply the largest current size and let the store scale down, rather than maintaining a separate set for every display that has ever shipped.
What actually converts in a screenshot set
- Image one: the single core benefit, stated as an outcome rather than a feature name.
- Image two: proof — real data, real content, or the result a user gets.
- Image three: the biggest objection answered, whether that is price, privacy or effort.
- Images four onward: secondary features, for the minority who keep swiping.
Frequently asked questions
What size do App Store screenshots need to be?
Supply the current largest iPhone display sizes — 6.9in and 6.5in — and the 13in iPad set if your app supports iPad. Smaller device sizes are scaled from those automatically.
How many screenshots should I upload?
Use the full allowance, but design the first three as if they are the only ones anyone sees, because for most visitors they are.
Do device frames help conversion?
Marginally, and mainly for clarity rather than persuasion. A plain screenshot with a strong caption consistently beats a heavily decorated frame with weak copy.
