When you export photos from Fulcrum, they are always default saved in the JPEG format. The file sizes of each JPEG image file is dependent on the resolution settings within the Fulcrum mobile apps for Android or iOS, or the original attached image file (if taken with a separate camera). They can be converted after export through any image converter or image editing software to a format of your choice.
Thank you so much for taking the time to send us your thoughts. We're always trying to improve Fulcrum and customer feedback helps tremendously.
