No EXIF data will be lost
Briefly, EXIF data is a bunch of fields storing information about what were the camera settings when the shot was taken. In this way you can learn about exposure, focal distance and a lot of issues regarding how to take a picture. EXIF data also contain a field for the camera model.
Recently, EXIF data becomes more and more useful and important. It can be used and displayed on many applications and websites. But many free photo editing softwares may lost EXIF data after save/save-as your picture files. That will be very terrible thing, because you can hardly recover the lost data which may contains very important informations for you.
Photo Toolbox was designed to keep all the EXIF and IPTC data in the original photo file. While saving or saving-as, the metadata will be totally copied into the target file, nothing you will lost!
And if you don't want to keep EXIF data into your new saving file. There is an option can be used to do this.

The above picture is the JPEG Encoder Options dialog which will be popup before saving / saving-as image file. You can check the CHECKBOX to keep your metadata, and uncheck it to clear the metadata.
Note: The save features are disabled in TRIAL VERSION, you can only see this dialog after purchasing a FULL VERSION.
