When using Watermarkup, currently we are creating a font-size picker, but you can still resize the watermark, text, and logo easily with a few simple steps.
Step 1: First you need to click on the watermark, text, or logo you want to edit and resize.
Step 2: You will see that there are several small squares around the watermark. You move your computer mouse into the corners or the small squares. Your mouse will change its symbol. And now you can use your mouse to change the size by holding left click and moving the pointer.
