To process a batch of pictures, I am looking for experts. There are no restrictions on photoshop, ACDSee and other software. I can batch process the problem of cropping and white edges. The specific requirements are as follows:

Just don’t save it in jpeg format when saving?

Once it is saved in jpeg format, it will fill in automatically. White is the background color

Should it be saved in png format? Can png save transparent areas?

The next time it is called, there will only be a watch? There will be no white background
