If your application has to show a user a PDF, you can send them the file or you can render it. Doconut does the second, inside your own .NET application. You can also see what that rendering looks like without installing anything: the free PDF viewer runs on the same engine, takes a file up to 25 MB, and deletes it when you close it.

Annotation, When the Workflow Needs It
Displaying a document is the base viewer. Marking one up is the Annotation plugin, licensed separately — one of four, alongside Converter, DICOM and Search. With it, reviewers can highlight passages, leave notes, add shapes and stamps, and save the annotated result as a PDF.
Worth knowing which side of the line a feature sits on before you plan around it. The free viewer on Doconut.app has no annotation at all: it reads, zooms, searches text and prints, and nothing you do there changes the file.
Integrate Doconut with Ease Across Platforms
The .NET viewer library works with ASP.NET WebForms, MVC, .NET Core and Blazor. Rendering happens on your server, so the browser installs nothing — and so the processing cost is yours to size for.
Support for Multiple Formats and Cloud Storage with Doconut
With Doconut.com, you're not just getting a PDF viewer. You're getting a platform that supports multiple document formats and storage options, from local files to cloud storage like Amazon S3 and Azure Blob Storage. This means Doconut is not just a PDF reader; it's a complete document viewing solution tailored to your business needs.
More Than Just a PDF Viewer
In summary: the SDK renders 75 file extensions across 18 families, not only PDF, so the same component handles the DOCX, the DWG and the MSG attached to the same record. It is installed in your environment and makes no calls to Doconut servers.
