Smart resizer
Automatically resize 1 key visual into every ad format you need, brand-safe at every size.
Resizing one approved visual into multiple ad formats is one of the most tedious jobs of any campaign.
Smart Resizer does it for you automatically and intelligently. Instead of cropping your ad to fit each format, SecretSauce rebuilds the composition, extending backgrounds and repositioning elements, so your ad looks right at every size.

When to use it
Use Smart Resizer when you're running campaigns across multiple platforms and need every format ready fast.

How to use Smart Resizer
- Open Image Studio from the left menu
- Select Smart Resizer
- Upload your image. This is the creative you want to adapt: a product shot, a campaign image, or a hero visual.
- Choose your platforms or enter custom dimensions. Smart Resizer generates every format from your single image.
- Tap Generate. You can see how many credits it costs to generate the resize before tapping.
When it's done, download your images directly from the right side panel. Every format is ready to upload.
