What is the best way to save pictures in a lossless format?

When I right click and "save image as" the part that says "save as type" only gives two options "JPG file [.jpg]" and "all files".

Do I have to use irfanview or something to save the images as PNG or BMP bit map?



P.S.
what is the best lossless image format PNG, BMP bitmap or something else?

I want to be able to re copy all my photos and pictures on flash drives over the years without worrying about loss.

What program are you trying to save them as?

Use PNG. JPG is lossy.

Images don't lose quality when you copy the file, just if you reencode them into other formats or run it through a couple passes of a lossy format like JPG.

Whenever you drag and drop files you get an exact 1:1 binary copy.

It only shows up as JPG because that is the file type the image currently is. If you search for a PNG image and right click to save, you'll see PNG is the default option. You won't lose quality simply by copying a picture in it's current format, such as copying a JPG picture as a JPG doesn't reduce quality.

If you have the original lossless image, the best formats would be RAW, TIFF, or BMP. JPG is lossy, and PNG is mainly for images with transparency.
