How to set the background color to transparent?

1. Boot into the computer main interface first, find and open the PS software in the computer main interface, then double-click the picture layer to unlock it, and click OK in the pop-up dialog box.

2. Then find and click "Select" in the menu option above PS, and then find and click "Color Range" option under the selected page. Next, move the mouse pointer to the picture in the pop-up dialog box. At this time, the mouse pointer becomes a straw and clicks on the white background of the picture.

3. Enter the desired value in the color tolerance, and then click OK. The value is between 1 and 200, and the larger the value, the better. Then click the "Delete" key on the keyboard.

4. Next, save the modified picture as a picture in png format. After completing the above settings, you can use PS software to remove the background color of the picture and turn it into a transparent background.

Using a mobile phone (such as Huawei mate 30 Pro, emui 10) can also change the picture into a transparent background. Unlock the mobile phone first, find and open the picture editing software on the main interface of the mobile phone, then select optimized matting in the right navigation bar, then select automatic matting, determine the range, and click Save as transparent background.
