Compress Images for Google Ads Campaigns
Google Ads display campaigns require images under 150KB for responsive display ads. ImageGates helps you compress your ad creatives to meet Google's strict file size limits while keeping your visuals sharp and click-worthy.
Google Ads image asset specifications
Responsive display ads require several ratios, and Google will not serve a placement whose ratio you have not supplied. Every asset shares the same 5 MB ceiling but the ratio set is what limits reach.
Exact specifications:
- Landscape: 1200×628 px (1.91:1)
- Square: 1200×1200 px (1:1)
- Portrait: 960×1200 px (4:5)
- Logo: 1200×1200 px square and 1200×300 px landscape
- File size ceiling: 5 MB per asset
What causes a rejected or degraded result:
- Supplying only a landscape asset, which excludes most mobile placements.
- Text covering more than about 20% of the image, which reduces delivery.
- Logos with transparent backgrounds that disappear on dark publisher pages.
Preparation order that avoids rework:
- Crop the same source to 1.91:1, 1:1 and 4:5 rather than stretching one file.
- Resize each to the recommended pixel size and compress under 5 MB.
- Keep the focal subject centred so every crop still works.
