BMP：是一种与硬件设备无关的图像文件格式，使用非常广。它采用位映射存储格式，除了图像深度可选以外，不采用其他任何压缩，因此，BMP图像所占用的空间很大。JPG：使用的一种失真压缩标准方法，24 bit真彩色，不支持动画、不支持透明色。JPEG的压缩方式通常是破坏性资料压缩（lossy compression），即在压缩过程中图像的品质会遭受到可见的破坏。一张图片多次上传下载后，图片逐渐会失真。

結果 (英文) 1:

BMP: is nothing to do with a hardware device image file format, use very wide. It uses a bit map storage format, in addition to the image depth Alternatively, without using any additional compression, thus, a large space occupied by BMP images. JPG: a lossy compression using standard methods, 24 bit true color, does not support animation, does not support the transparent color. JPEG compression method is usually lossy compression (lossy compression), that is, during the compression of the image quality will suffer visible damage. After a picture upload and download times, the picture gradually distorted.

結果 (英文) 2:

BMP: Is an image file format that is independent of hardware devices and is widely used. It uses a bit map storage format and does not use any compression other than the image depth optional, so BMP images take up a lot of space. JPG: A standard method of distortion compression, 24 bit true color, does not support animation, does not support transparent color. JPEG compression is usually destructive data compression, i.e. the quality of the image during compression is exposed to visible damage. When a picture is uploaded and downloaded multiple times, the image gradually becomes distorted.

BMP: it is a kind of image file format independent of hardware device, which is widely used. It uses a bit mapped storage format. Except for the optional image depth, it does not use any other compression. Therefore, BMP image takes up a lot of space. Jpg: a distortion compression standard method used, 24 bit true color, does not support animation, does not support transparent color. The compression mode of JPEG is usually lossy compression, that is, the quality of image will suffer visible damage during the compression process. After a picture is uploaded and downloaded many times, the picture will be distorted gradually.
