Add Signature to PDF
Draw, type, or upload a signature and place it on any PDF page
Drop a PDF to sign
One PDF up to 150 MB. It is processed in your browser.
This adds a visual signature to the document. It does not create a certificate-backed digital signature or audit trail.
What does Add Signature to PDF do?
It places an image of your signature on one or more pages of a PDF, right in your browser. You can draw it, type your name in a script style, or upload a scanned signature, then position it exactly where it belongs and download the signed copy. The original page content stays intact underneath.
How to use
- 1.Drop a PDF or browse for one.
- 2.Create a signature: draw it, type your name, or upload an image (optionally turning a white background transparent).
- 3.Click the page to place the selected signature, or use "Place in center of page".
- 4.Drag to move, drag the corner handle to resize, or type exact X, Y, and width values. Duplicate or delete placements as needed and switch pages to sign more than one.
- 5.Click Create signed PDF and download the result.
Placement and accessibility
- •Positions are in PDF points (72 points = 1 inch) measured from the top-left corner of the page as you see it.
- •Pages that are rotated inside the PDF are handled so the signature appears upright where you placed it.
- •Every placement can be moved with the arrow keys (Shift for 10-point steps), resized with + and −, and removed with Delete.
- •The aspect ratio of each signature is always kept.
Visual signature, not a digital certificate
This adds a visual signature to the document. It does not create a certificate-backed digital signature or audit trail, and it does not prove who signed. If the PDF already contains certificate-based signatures, saving a modified copy can invalidate them. Password-protected PDFs must be unlocked first. Everything runs locally in your browser; the PDF and your signature are never uploaded.
