Which format can store my images best? Which format produces the smallest files?

The following table compares the features of these file formats. Color modes A color mode dictates the maximum number of colors an image file can store. We define low-color as modes ranging from 2 up to 256 colors. We define high-color as modes beyond 256 colors.
Today's computers can usually display 16 million colors, which is also the usual number of colors in photo files. All these image formats support high-color images, with the exception for GIF.

I only consider open formats, not proprietary formats. The file sizes are approximate, because the effectiveness of compression varies depending on the data.
