What the Sign PDF tool does
The tool lets you draw a signature on screen or use an image, placing it visually before final export. It is especially useful for contracts, approvals, forms, and internal workflows where speed and privacy both matter.
Because the workflow runs locally in the browser, users avoid sending contracts, approvals, internal forms, and sensitive documents to external servers, which strengthens privacy and operational control.
