The old workflow was one design tool per platform: a Facebook post made one way, an Instagram version redone from scratch, an X post squeezed in separately. The trend now, especially among solo creators and small social teams, is the opposite — build the asset once, and let each platform's specific sizing be a final export step rather than a full redesign.
This is precisely what Export for Other Platforms is built for: build your post once in the Image Post Generator, then export it re-cropped to Instagram's 4:5/1:1/3:4, X's 16:9/1:1/3:4, and LinkedIn's 4:5/1:1/16:9 — all from the same original design, downloaded together as one ZIP.
The practical workflow: design once in the Image Post Generator → save it with My Posts so it's never lost → export it to every platform you post to → repeat with the same visual style next time. Four tools, one consistent process, instead of starting over per platform every time.
You don't need a separate design process for every platform you post to — you need one strong post and a reliable way to resize it correctly.
Build once. Publish everywhere.
