Frequently asked questions

Can DocuVieware scan documents directly from a web browser?

Yes. DocuVieware includes built-in TWAIN acquisition for HTML5 document scanning. Because a browser cannot talk to a scanner on its own, users install a lightweight local TWAIN connector once; DocuVieware serves the installer itself so the version always matches. Any TWAIN-compliant device works, acquired pages land straight in the viewer, and the result can be saved as PDF/A or multipage TIFF. See the TWAIN acquisition guide for the JavaScript API that customizes the flow.

Is DocuVieware suitable for viewing sensitive documents?

DocuVieware is a zero-footprint HTML5 viewer, so nothing is installed on the client for viewing, and documents are served from your own .NET application. You control access, editing, viewing, and printing rights; redact content permanently with permission-based redaction; sign with certificate-backed digital signatures; and archive in PDF/A. For full data control, deploy it on-premises as described in the deployment guide.

Can DocuVieware be deployed on-premises?

Yes. DocuVieware ships as on-premises software in Nutrient .NET SDK, through an ASP.NET API for MVC and Web Forms, so your web application and its documents stay on servers you run. A cloud-based service is also available through the PassportPDF ecosystem for teams that prefer zero maintenance.

Which .NET web frameworks does DocuVieware support?

DocuVieware integrates with ASP.NET Core, ASP.NET MVC and Razor, and ASP.NET Web Forms on the server, and its JavaScript client API works with frontends such as Angular, React, Node.js, and PHP. Step-by-step setup for each stack is in the DocuVieware guides.

How does DocuVieware relate to GdPicture.NET?

DocuVieware is powered by GdPicture.NET, the document imaging and processing engine behind Nutrient .NET SDK. A DocuVieware development license grants access to every GdPicture.NET feature — including OCR, barcode recognition, format conversion, and image processing — so you can load a document in the viewer and process it server-side. Read more in the DocuVieware and GdPicture.NET guide.

How do I get started with DocuVieware?

Start on the DocuVieware product page for an overview and licensing. Then follow the getting started guide to add the viewer to a .NET web application. A free trial of Nutrient .NET SDK includes DocuVieware.
