We do not sell the WinForms PDF Viewer control separately. It is only available for purchase as part of the Syncfusion WinForms suite, which contains over 100 WinForms controls, including PDF Viewer. A single developer license for the Syncfusion Essential Studio for WinForms suite costs $995.00 USD, including one year of support and updates. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team to see if you qualify for any additional discounts.

You can find our WinForms PDF Viewer demo on

GitHub location.

No, our 100+ WinForms controls, including PDF Viewer, are not sold individually, only as a single package. However, we have competitively priced the product so it only costs a little bit more than what some other vendors charge for their PDF Viewer alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 100+ WinForms controls for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.

No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.

A good place to start would be our comprehensive getting started documentation.
