One high-performance C++ core with native bindings for .NET, UWP, Swift and WebAssembly. Built and battle-tested in Drawboard PDF, used by 4 million people.
Most teams building document workflows get stuck between two bad options. We've been on both sides, so we built our own engine. Now we're opening it up.
Years of edge cases before your engine renders real-world PDFs reliably.
High costs, rigid terms and a vendor that doesn't know your users.
A proven engine, tailored to your needs, with engineers who answer your questions.
Performant rendering of a wide range of PDF documents, specialising in complex AEC drawings.
Add and edit optional content layers.
Sign documents with a digital certificate.
Snap to content while marking up, for more accurate results.
Permanently remove sensitive content from documents.
Built to run on-device for interactive apps, or on a server for batch processing.
Stop maintaining a different library per platform. The same engine runs on-device for interactive apps and on the server for batch processing.
| Platform | Bindings | Runs on |
|---|---|---|
| .NET on Windows and Linux | C# | Server |
| UWP | C# | Client |
| iOS and macOS | Swift | Client |
| Web (WebAssembly) | JavaScript | Client |
Add PDF viewing and markup to your product without building an engine.
Fast handling of large drawings and precise snapping for markup.
A more flexible partner on pricing, support and roadmap.
Process and secure documents on the server at scale.
We're working with a small group of early partners on how the SDK is packaged, licensed and supported. Drawboard can tailor an SDK solution to your specific needs, with dedicated support under an SLA.
