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
JPEG 25,049,666 24,379,710 24,379,392 2.67% 2.68%
BMP 22,616,550 8,175,537 12,507,968 63.85% 44.70%
MP3 30,154,228 29,931,105 29,897,355 0.74% 0.85%
MP4 396,231,169 395,504,834 394,879,582 0.18% 0.34%
AVI 108,300,864 102,183,647 104,713,964 5.65% 3.31%

Word 25,731,072 15,337,081 16,611,768 40.39% 35.44%
Execl 34,787,328 5,293,376 8,405,348 84.78% 75.84%
txt 26,655,349 12,380,134 14,032,890 53.55% 53.55%

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
JPEG 25,049,666 24,465,063 24,392,549 2.33% 2.62%
BMP 22,616,550 10,038,519 12,506,942 55.61% 44.70%
MP3 30,154,228 30,025,189 29,896,747 0.43% 0.85%
MP4 396,231,169 394,879,532 399,346,666 0.34% -0.79%
AVI 108,300,864 101,627,786 104,713,842 6.16% 3.31%
RMVB 449,221,835 449,471,757 447,630,692 -0.06% 0.35%
MKV 564,619,749 568,724,028 563,811,006 -0.73% 0.14%
Word 25,731,072 14,975,597 16,604,056 41.80% 35.47%
Execl 34,787,328 3,413,170 8,403,420 90.19% 75.84%
txt 26,655,349 12,344,669 14,009,640 53.69% 47.44%
结果中有负数,说明文件压缩后比压缩前大了。

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
JPEG 25,049,666 24,379,710 24,464,648 24,344,331 2.67% 2.34% 2.82%
BMP 22,616,550 8,175,537 10,038,458 11,906,306 63.85% 55.61% 47.36%
MP3 30,154,228 30,154,846 30,025,142 29,878,227 0.00% 0.43% 0.92%
MP4 396,231,169 396,231,255 396,231,281 396,231,327 0.00% 0.00% 0.00%

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。
