Files too large
Oversized assets require compression before they can be trafficked.
Unsupported formats
Files arrive in formats that do not match the placement requirements.
Last-minute corrections
Ad ops becomes the final checkpoint for issues that should have been caught earlier.

Final asset revalidated
When an upload is close to spec, DropAsset may apply compatible downscaling, compression or supported format conversion so trafficking receives a Ready file that matches your requirements.
- Compatible downscaling when the creative can be reduced safely
- File compression within configured size limits
- Supported format conversion when requirements allow it
DropAsset does not stretch creatives, force a crop to fake compliance or automatically upscale an image to pass validation.
