Quark browser itself does not provide handwritten signature function, but you can try to use the scanning king function in Quark to generate electronic handwritten signature. The specific steps are as follows:

1. Open Quark APP and click Quark Learning icon to enter.

2. Click the handwritten icon at the top of the paper page.

3. Click the shoot button at the bottom of the page to shoot the paper that needs to be handwritten.

The above is the method of generating electronic handwritten signature by quark browser, and I hope it will help you.
