格式化，查找和阅读其规范，了解其压缩质量，压缩率与质量和其他相关属性。这个主题太大了，无法在快速回答中涵盖，但您可以轻松找到适合您目的的合理选择;只做一些最小的研究和实验。

Please see my comment to the question and this: http://en.wikipedia.org/wiki/Lossless_compression[^],
http://en.wikipedia.org/wiki/Image_compression[^].

For compression specific to images and standard image compression algorithms, please see:
http://msdn.microsoft.com/en-us/library/ms142147.aspx[^],
http://msdn.microsoft.com/en-us/library/9t4syfhh.aspx[^],
http://msdn.microsoft.com/en-us/library/system.drawing.imaging.imageformat.aspx[^].

In each format, find and read its specification, to learn about its compression quality, compression rate vs quality and other related properties. This topic is too big to cover in a Quick Answer, but you can easily find a reasonably good option for your purpose; just do some minimal research and experimenting.
