Any size image can be uploaded into AssetFlow, however these will be resized during the upload process. The media management tool used in the system is designed to retain the best visual quality while reducing the file size considerably, meaning that the system can remain as efficient as possible. 

The constraints for the image file size reduction are implemented by the third party tool Cloudinary. We use the "q_auto:good" quality resizing setting, which you can find out more about here

(Please note, it is not possible to predict the output image size as this will be unique to each image.)
