Considering that the reason is that a large number of pictures are inserted into the document, the size of the pictures is adjusted appropriately, and some unnecessary parts of the big pictures are directly cut out with the cutting tool of Word. However, after saving, it is found that the file size has not changed and the editing speed of the document has not improved. -.In fact, by default, the original image information in the document will not be erased, but it is invisible on the screen. To really change the size of a picture inserted into a Word document, you should follow the following steps: 1. After cutting and changing the size of all the pictures to be processed, right-click any picture and select the Format Picture menu item from the pop-up menu. 2. In the opened dialog box for setting picture format, select the picture tab and click the compression button in the lower left corner. 4. Click OK to finish the setup. In this way, those irrelevant image data are removed from the Word document, and the purpose of "slimming" the Word document is achieved.
