Reduce a mockup file without losing the message

Put it into practice

1. Confirm the actual display or upload requirement.
2. Avoid an oversized export when 1× is sufficient.
3. Compare format options while inspecting small text.

What this looks like

A detail to keep clear

Aggressive compression can damage fine interface text before it noticeably affects large shapes.

Using MockupX

MockupX exports PNG and JPEG, with WebP and 2× output available to Pro accounts. Export requires sign-in, and free exports carry a watermark. A transparent background remains transparent only in a format that supports it. Inspect the downloaded file, not only the editor preview.

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.
