Why is “JPG” so "fat"? 1 second to get the PS straight out JPG super problem

When using PS to do graphics, you often encounter problems with straight out JPG, especially some online download templates, even if the pattern is very simple, but the generated JPG is also more than a dozen MB. 

The strangest thing is that whether it is to stamp the layer, or to reduce the quality of JPG, or even create a new JPG to drag the original layer to the past, all can not get this problem. 

So today, Xiao Bian teaches everyone a good way to solve the problem of straight out PS in 1 second. The most important thing is that this little trick has no influence on the picture quality.

The whole step is divided into 4 steps:

　　1. Press Ctrl+Alt+Shift+E to stamp the layer;

　　2. Right-click on the stamp layer of the mouse, click on the "Duplicate Layer".

　　3. In the pop-up dialog box, select "Document" as "New";

4. PS will generate a new picture later, the content is the original stamp layer, save the picture as JPG format;

　　A magical scene appeared, and the newly generated JPG was reduced from the original 13.7MB to 304.5KB, which was a full reduction of 46 times. The most important thing is that the quality of the picture is not a little lost (JPG level 12), very shocking.

Postscript

　　Many small partners ask what the principle, in fact, very simple is, this is the smart object used in the file.

 　　Since many online templates (especially prototypes) use smart objects, the high-definition materials embedded in such smart objects are not disconnected from the original material when they are saved. 

Therefore, although it seems that you just generated a picture, but it actually contains a lot of HD material, naturally it seems to be "obese" a lot.

　　This method in the text actually interrupts the connection between the stamping layer and the smart object, and the generated image naturally restores its original appearance. 

In addition, if you find that the downloaded image is zoomed or simply edited, the PS needs to run for a long time, and most of the reason is also the same. You can also try this method, there will be amazing effects!
