Put it into practice
- Capture equivalent states before and after.
- Align the frames and use consistent cropping.
- Label the versions clearly outside the screenshot if needed.
What this looks like
A redesigned search panel is shown with the same sample query in both images.
A detail to keep clear
Changing the data and viewport as well as the interface makes the comparison harder to interpret.
Using MockupX
Browser framing communicates that the image shows a web product. Choose the browser appearance and adjust image sizing in MockupX, but use the original screenshot to decide which content matters. Decorative browser chrome does not make the underlying interface interactive.
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.
