在图像文件中查找压缩类型

I want to find the compression type for an image that is currently stored as .bin file (dont know why its stored like this it just is) but my question is should I find the compression type while its in a .bin file or should I do it when I convert to a .tiff file. I done tons of research and not sure whats the best way. If anyone can give me some feedback that will be wonderful. Thanks!I want to find the compression type for an imag
