Sign a PDF with your handwriting

Draw a handwritten signature using touch, pen or mouse. Place it on a PDF page and download the modified document. This is a visible signature image only: it is not a cryptographically verifiable certificate-based digital signature and does not establish signer identity.

Browser-only file processing · No login · No watermark

How it works

1. Open a PDF in LHTSOFT PDF.
2. Choose Sign PDF, draw your signature and click Use drawn signature.
3. Click the PDF page to place it and download the signed-looking document.

Beta release: features are introduced only after validation. General-purpose existing PDF text replacement, certified signatures, office document conversion and guaranteed irreversible redaction are not supported. The editor has narrowly limited experimental text replacement. Keep a backup of your originals.
