Prepare a 1200×1200 ad image
Create square campaign assets at 1200×1200, the size Google lists for common square image and logo placements. Google Ads recommends 1200×1200 for responsive display ads, with lower minimum dimensions accepted in some campaigns.
The output keeps the source file format. Upload JPEG or PNG sources when the destination requires one of those formats.
Square cover crop
Cover mode fills the entire 1:1 frame without distortion. A landscape source is trimmed on the sides, while a portrait source is trimmed at the top and bottom.
Keep logos, product edges, and text away from the outer boundary. Ad placements may apply their own masks or responsive crops after upload.
Batch campaign assets
Add several source images to produce a consistent square set. The generated filenames include 1200x1200, which helps distinguish the square exports from landscape and portrait campaign files.
