How to make Meta ad creatives and Google PMax assets with AI — in minutes, no designer, no Canva, and no manual resizing needed.

If you're running Meta and Google PMax ads and you're stuck making one creative size or paying someone to resize every asset manually, this AI workflow fixes that. In the video I start with one product link and one simple prompt to generate a 1:1 (1080x1080) static and a 1080x1920 video. From there, the AI adapts them into every size Meta and Google PMax need — turning a single brief into a full creative pack ready to upload to the ad platforms.

The tool I use is Creatify — the agent adapts that same creative into the other sizes, such as 1200x628 and 1080x1920, optimised for Google PMax placements. It keeps the creative direction and just adjusts the layout to fit each one.

I went from making one creative size to a full pack of five-plus assets from a single starting brief, cutting what used to be hours of resizing down to a few minutes. If you want to skip paying a designer or rebuilding ads from scratch, this is the fastest path I've found.

The approach:
1. Start by generating one 1:1 square static that works on both Meta and Google PMax
2. Adapt that static into horizontal and vertical sizes with a simple prompt
3. Test and scale the winning ad creatives

Works for e-commerce brands, marketers, and agencies that do ad testing across multiple platforms — any DTC business running meta and google PMax ads.
