主流壓縮軟體壓縮率實測（圖文詳解，揭秘你不知道的)

注：以下資料均采用“最好”壓縮得出。

一、使用winra工具對目标檔案進行壓縮，得出如下結果(winrar支援兩種格式壓縮)：

檔案格式壓縮前大小（位元組）rar壓縮後大小（位元組）zip壓縮後大小（位元組）rar壓縮率zip壓縮率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%

見圖表：

二、使用好壓對目标進行壓縮，得出結果如下：

檔案格式壓縮前大小（位元組）7z壓縮後大小（位元組）zip壓縮後大小（位元組）7z壓縮率zip壓縮率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%

結果中有負數，說明檔案壓縮後比壓縮前大了。

三、使用360壓縮後，結果如下：
