Frequently asked questions
How do I sign a PDF online for free?
Upload your PDF, draw your signature with your mouse or finger (or type your name), choose the page and position, click Add Signature and download. It is free, needs no sign-up and adds no watermark.
Is this the same as a digital signature (DSC)?
No. This tool places a picture of your handwritten signature on the PDF — perfect for everyday forms, letters and approvals. Some government or legal filings need a certified digital signature (DSC) instead; check the receiver's rules.
Is my PDF uploaded to a server?
No. Signing happens inside your browser — your document and your signature never leave your device.
Can I sign on my phone?
Yes. The signature pad works with touch — draw with your finger, choose the position and download, all on your phone's browser.
Where can I place the signature?
Bottom right, bottom left, bottom centre or top right — on the first page, the last page, or every page. Three sizes are available.
My signature looks messy. Any tips?
Draw slowly and a little larger than feels natural, and use the Medium or Large size. You can Clear and retry as many times as you like.
