Hi - I'm making a web survey where possibly several hundred images could be uploaded. Does anyone know if these images get compressed before saving to the file gdb on ArcGIS online?
Images collected in surveys are not really compressed. However, you can set the desired image size on the Settings > Images tab in Survey123 Connect. There are 4 different size options - please see this help topic,

Hope this helps,
I uploaded some images and downloaded the resulting file geodatabase. Based on this I think the answer is no
