Put it into practice
- Identify the upload field in the store console.
- Read its current specification.
- Build a composition for that asset rather than recycling another format unchanged.
What this looks like
A Google Play feature graphic is planned separately from portrait in-app screenshots.
A detail to keep clear
The same file is not automatically appropriate for every store asset field.
Using MockupX
Store specifications are maintained by Apple and Google and can change. Check the relevant console's current requirements for the device family and asset type. MockupX creates images; it does not submit listings, validate every policy or guarantee approval.
Check the result
Keep the original screenshot, then review the exported file at the size where people will see it. Check the message, the visible interface and the final crop separately. For a handoff, record the destination and the approved file so another person can distinguish the final version from a draft.
References and further reading
Use the official references for format behavior and current destination requirements. The composition advice above is a practical design approach, not a promise of platform approval.
