Can I save the Scanned photos in JPEG format instead of PNG?
As of the moment, the Clickfree App doesn't have the option to make the scanned images saved in JPEG. Once you scanned a photo and save it, the file format is PNG.
PNG files are mostly for digital image files and they utilize document compression, but not as much as JPEGs do. But, if you're scanning a photo then PNGs can be good because they're considered “lossless”, meaning they will produce a less pixelated file.
