Put it into practice
- Choose one product moment.
- Use a short headline and one dominant screenshot.
- Inspect the image at phone width.
What this looks like
A release card shows the new search panel instead of the entire admin dashboard.
A detail to keep clear
A detailed interface may require a linked walkthrough rather than more tiny text inside the image.
Using MockupX
A social composition is a separate design from the original product screenshot. Use the output frame to establish shape, then test the exported image in the actual destination preview. MockupX does not publish posts or guarantee a platform will display every pixel without cropping.
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.
