Most office workers will meet the demand of electronic signature in their daily work. If you simply take an electronically signed photo and paste it on the contract, sometimes the customer will not recognize it. Students are taught to make a vector electronic signature with PS, and there is no background color. Learn this trick, it will come in handy in the future!

First, we hand-write a signature on the paper, then take a photo, send it to the computer, and then cut it to the right size. Then open PS, and drag the captured picture into the software to open it.

Select the magic wand tool in the figure, and press and hold the left key to select the second one.

After selecting the magic wand tool, after clicking in the blank area of the picture, the signature and the surrounding border will flash.

Press the delete key on the keyboard to delete the white paper around the signature. At this point, you can see that the signature background is mosaic graphics, and the basic red circle is the part that has not been deleted.

According to the method just now, click on the gray-black area here and press the Delete key, and the other two parts will follow suit.

At this point, the vector electronic signature is done.

Next, save the finished file and select OK.

We experiment with a document with a green background, and we can see that this is what we want.
