Unity能很好压缩其他软件输出的文件格式，所以除非你已经是一个正确分辨率的JPG文件否则最好使用无损格式的纹理（不要手动进行压缩）。

Unity takes care of compression for the output platform, so unless your source is already a JPG of the correct resolution it's better to use a lossless format for your textures.

无损的压缩虽好，但是为了在大型数据库中节省少量的空间而重新格式化和存储接收的数据，会导致更多问题，实属不值。

Lossless compression is fine, but reformatting and storing received data for a small percentage gain in space in a large database will cause more issues than it's worth.

GIF代表“图形交换格式”并使用TIFF(标记图像文件格式)图像相同的无损耗lzw压缩。

GIF stands for "Graphics Interchange Format" and employs the same lossless LZW compression that TIFF images use.
