Add a handwritten signature to a PDF

Coverton · Published October 3, 2026

Coverton adds a drawing of your signature to a PDF. It is not certificate signing or identity verification.

Draw your signature

Keep the original PDF. Draw with a mouse or touch, undo strokes or clear them. Choose black or blue and download a transparent PNG copy if needed.

Place and check

Choose a page and adjust position and width by dragging, numbers or arrow keys. Reopen the saved PDF to check pages, rotation and placement. Redrawing clears previous placements.

Support and limitations

Use unencrypted PDFs up to 100 MB, with up to 100 placements. A drawing does not certify identity or document integrity. Editing a certificate-signed PDF may invalidate its signature.
