1. Open wpsoffice, find the file to be signed and open it. 2. Click Edit to enter edit mode. 3. Click the Tools button. 4. Hold down the navigation menu and drag to the left to the brush.

5, will open with your fingers. 6. Sign your name in the corresponding position of the document, and then click the Save icon. Or, we sign a blank A4 paper by hand, and then scan the signature and save it in the computer, or shoot it with a mobile phone, and then import it into the computer and save it in a picture format. Then open a wps text document, click the position where you need to insert the signature, and then select Insert-Picture to insert the signature into the document. After insertion, you will find that the background color of the signature is very different from that of the document, that is, it is abrupt and printed in a rectangular shape. At this point, you need to make a simple setting to "integrate" the signature into the document. In wps text, there is the function of setting transparent color. Click the signature image and the image tool will automatically appear. Click the setting transparent color below, and then an icon similar to a small straw will appear on the mouse. Click the signature image, and the background color of the image will become transparent.

Click the signed picture again, select the layout type of the picture as the lining below the text in the tool options on the right, and then adjust the position and size of the signature. You can copy the signature to another location in the document. If you use officeWord instead of WPS text, the version is relatively low, and you may not have the function of setting transparent color. Then you can double-click the picture, enter the picture format setting, adjust the contrast of the picture to 60- 100%, or integrate the signature background into the document.
