The invention discloses a method for reducing the size of a mobile electronic magazine file. The method includes the steps that firstly, an image popped up in a mobile electronic magazine needing to be manufactured is manufactured to be a source image (ori.png) of the png format; secondly, the image popped up is manufactured to be an output image (out.jpeg) of the jpeg format; thirdly, the source image (ori.png) is copied to form a mask image (mask.png) of the png format, and the mask image (mask.png) is manufactured to be an image, wherein the alpha channel of the image is not changed, and the color of the image is pure; fourthly, the mask image (mask.png) is added to the output image (out.jpeg) through mask attributes on mobile equipment. Through the method, the final displaying background of the image popped up is transparent, good visual experiences are achieved, and the size of the whole mobile electronic magazine is greatly shortened.
