Sign PDF is a free, browser-based tool for stamping a typed or image-based signature onto a document. This creates a visual signature mark, not a legally binding cryptographic digital signature — for contracts requiring verifiable e-signatures, use a dedicated e-signature service.
How to use the Sign PDF
- Upload your PDF.
- Enter the page number and position for your signature.
- Either type your name or upload a signature image — the image takes priority if both are set.
- Download the signed PDF.
