About Sign PDF

The print-sign-scan workflow still costs millions of people 10 minutes per document. For a single signature on a standard contract that is an absurd amount of friction that digital tools eliminated years ago. Mini Tool lets you draw your signature with a mouse or finger, type it in a handwriting style, or upload an image of your signature. Place it anywhere on any page, resize to fit, and download the signed PDF. No account needed, no monthly subscription, no file sent anywhere.

How to use Sign PDF

  1. Upload the PDF: Open the contract, form, or letter you need to sign.
  2. Create your signature: Draw with a mouse or stylus, type a styled signature, or upload a saved PNG.
  3. Place and resize: Position the signature on any page and scale it to match the document layout.
  4. Download the signed PDF: Save a flattened copy ready to email or archive.

Visual signatures vs certificate signing

Most everyday PDF signing is visual: an image of your signature placed on the page, similar to signing with a pen on paper. Certificate-based digital signatures use cryptographic keys and are common in enterprise procurement systems.

Mini Tool focuses on fast visual signing for contracts, forms, and internal approvals. If a counterparty requires PKCS#7 certificate signing, you will need specialized certificate software in addition to a visual signature.
