注:以下数据均采用“最好”压缩得出。
 
一、使用winra工具对目标文件进行压缩,得出如下结果(winrar支持两种格式压缩):
文件格式压缩前大小(字节)rar压缩后大小(字节)zip压缩后大小(字节)rar压缩率zip压缩率JPEG25,049,66624,379,71024,379,3922.67%2.68%BMP22,616,5508,175,53712,507,96863.85%44.70%MP330,154,22829,931,10529,897,3550.74%0.85%MP4396,231,169395,504,834394,879,5820.18%0.34%AVI108,300,864102,183,647104,713,9645.65%3.31%RMVB449,221,835447,904,871447,630,7440.29%0.35%MKV564,619,749564,222,464563,811,1620.07%0.14%Word25,731,07215,337,08116,611,76840.39%35.44%Execl34,787,3285,293,3768,405,34884.78%75.84%txt26,655,34912,380,13414,032,89053.55%53.55%
 
见图表:
二、使用好压对目标进行压缩,得出结果如下:
文件格式压缩前大小(字节)7z压缩后大小(字节)zip压缩后大小(字节)7z压缩率zip压缩率JPEG25,049,66624,465,06324,392,5492.33%2.62%BMP22,616,55010,038,51912,506,94255.61%44.70%MP330,154,22830,025,18929,896,7470.43%0.85%MP4396,231,169394,879,532399,346,6660.34%-0.79%AVI108,300,864101,627,786104,713,8426.16%3.31%RMVB449,221,835449,471,757447,630,692-0.06%0.35%MKV564,619,749568,724,028563,811,006-0.73%0.14%Word25,731,07214,975,59716,604,05641.80%35.47%Execl34,787,3283,413,1708,403,42090.19%75.84%txt26,655,34912,344,66914,009,64053.69%47.44%
结果中有负数,说明文件压缩后比压缩前大了。
见图表:
三、使用360压缩后,结果如下:
文件格式压缩前大小(字节)rar压缩后大小(字节)7z压缩后大小(字节)zip压缩后大小(字节)rar压缩率7z压缩率zip压缩率JPEG25,049,66624,379,71024,464,64824,344,3312.67%2.34%2.82%BMP22,616,5508,175,53710,038,45811,906,30663.85%55.61%47.36%MP330,154,22830,154,84630,025,14229,878,2270.00%0.43%0.92%MP4396,231,169396,231,255396,231,281396,231,3270.00%0.00%0.00%AVI108,300,864102,183,647101,627,762103,886,0545.65%6.16%4.08%RMVB449,221,835449,221,924449,471,733449,221,9950.00%-0.06%0.00%MKV564,619,749564,222,464564,619,915564,619,9870.07%0.00%0.00%Word25,731,07215,337,08114,975,36716,410,16640.39%41.80%36.22%Execl34,787,3285,293,3763,412,8457,716,33384.78%90.19%77.82%txt26,655,34912,380,13412,344,09013,584,15853.55%53.69%53.55%
见图表:
四、综合各工具最高压缩率的格式对比如下:
文件格式 winrar压缩率 好压压缩率 360压缩率
JPEG 2.67% 2.33% 2.67%
BMP 63.85% 55.61% 63.85%
MP3 0.74% 0.43% 0.00%
MP4 0.18% 0.34% 0.00%
AVI 5.65% 6.16% 5.65%
RMVB 0.29% -0.06% 0.00%
MKV 0.07% -0.73% 0.07%
Word 40.39% 41.80% 40.39%
Execl 84.78% 90.19% 84.78%
txt 53.55% 53.69% 53.55%
三种工具的压缩率对比图如下:
 
通过上面的实测,对于大家平时选择什么压缩工具,使用什么格式压缩,可以起到一定的参考作用。
