What Is the Sign PDF Tool?
The Sign PDF Tool lets you add your signature to a PDF document directly in your browser. You can draw your signature using a mouse, touchpad or touchscreen, or upload an existing signature image in PNG or JPG format.
Once your signature is ready, you can place it on one page, multiple selected pages or every page of the PDF before downloading the signed document.
Everything happens locally inside your browser. Your files remain on your device during normal use.
