About this tool

Sign PDF Online opens your document in the browser so you can place signatures exactly where you need them. Choose typed text (multiple handwriting and professional fonts) or upload a signature picture, drag the signature onto any page, then download the signed PDF. This is a visual signature overlay for everyday paperwork—not a certified digital certificate. For legally binding e-signatures in regulated industries, use an approved provider; for quick internal approvals, this tool is fast and private.
