Overview
The sign pro PDF app is the version of Wacom’s signing software you simply install and use. It opens a PDF, lets a person sign it by hand with a digital pen on a Wacom device, and saves the signed file — no development, no integration, and no change to the systems around it. Handwriting recognition also lets form fields and annotations be completed by pen rather than typed, which is what makes it practical for filling in a form as well as approving one.
It fits the situation most organisations actually start from: documents that need a real signature, arriving in ones and twos rather than thousands, from people who should not have to wait for an IT project. A manager approving a purchase order, an HR team completing an onboarding form, a clinic capturing a consent form at reception. The signature is captured with the biometric detail of how it was written, so the resulting document carries meaningfully more evidence than a scanned image of a signature would.
Two versions exist. The Standard version is free to download and covers straightforward signing. The Premium version adds enhanced functionality for organisations that need more from it. Both run on Windows with Wacom pen hardware and compatible third-party pen devices, support the ISO signature format, and include built-in encryption. Because it is a desktop application, deployment is a matter of installing it and pairing a signature pad — typically the same day.
The honest limitation: it automates nothing. Somebody opens the app, opens the document, and signs. That is exactly right for ad-hoc signing and exactly wrong for a high-volume process driven by another system — if hundreds of documents a day are generated by your CRM or core platform, you want the sign pro PDF API instead, so signing happens inside that workflow. Many organisations run both, and there is no conflict in doing so.

Frequently Asked Questions
What is the Wacom sign pro PDF app?
It is a Windows application for signing and filling PDF documents by hand with a digital pen. You open the document in the app, sign on a Wacom device, and save the signed file — no integration with other systems is needed.
Is sign pro PDF free?
The Standard version is free to download and covers straightforward signing. A paid Premium version adds enhanced functionality. Which one you need depends on the features your documents require, and we can advise on that.
Does sign pro PDF run on Mac, iOS or Android?
The app runs on Windows. If you need signing on iOS or Android, the sign pro PDF Enterprise API supports those platforms, integrated into your own application.
Can I fill in form fields as well as sign?
Yes. The app includes handwriting recognition, so you can write into forms and annotations with the pen and have it converted to text, rather than switching to a keyboard.
Is a signature made in sign pro PDF legally valid?
Electronic signatures are recognised under the UAE Electronic Transactions and Trust Services Law. sign pro PDF captures the handwritten signature with its biometric detail and supports the ISO signature format, which is what gives a signed document evidential weight.
Can the app sign documents automatically from our system?
No. The app requires a person to open and sign each document. For signing driven automatically by a CRM, ERP or document system, you need the sign pro PDF API instead.
