Retina Display Support
For high-resolution (retina) displays, you can upload images at 2x the standard dimensions. The platform will automatically detect and optimize these images for retina displays.
Example:
- Standard size: 300 × 250
- Retina size: 600 × 500 (2x width and height)
When uploading a retina image, ensure the dimensions are exactly double the standard size. The platform validates that the image is a 2x version of an accepted standard size.
Image Best Practices
- Optimize file size - Keep images under 2 MB while maintaining quality
- Use appropriate formats:
- JPEG for photographs and complex images
- PNG for images with transparency or text
- GIF for simple animations (if supported by placement)
- Design for retina - Consider uploading 2x versions for better quality on high-DPI screens
- Test visibility - Ensure text and logos are readable at the target size
- Follow brand guidelines - Maintain consistent branding across all creative sizes
Video Creatives
File Requirements
- Supported Format: MP4
- Maximum File Size: 50 MB

| Format | MP4 (video/mp4) |

Video Best Practices

Upload Validation
When uploading creative assets, the platform validates:
- File format - Must match accepted MIME types
- File size - Must not exceed maximum limits
- Image dimensions - Must match one of the accepted standard or retina sizes
- Video duration - Must be between 5 and 90 seconds
If validation fails, you'll receive a specific error message indicating what needs to be corrected.
Common Upload Errors
| Error Message | Cause | Solution |
|---|---|---|
| Invalid mime type | Unsupported file format | Use JPEG, PNG, GIF for images or MP4 for videos |
| File size exceeds limit | File too large | Compress image to under 2 MB or video to under 50 MB |
| Invalid dimensions | Image size not supported | Use one of the accepted dimensions listed above |
| Video duration invalid | Video too short or too long | Edit video to be between 5-90 seconds |
