Yes. Every part of the interface can be tailored. You can hide or extend toolbars, trigger custom workflows, apply brand themes, and even add overlays or custom buttons using our UI customization API.
What security features does the viewer SDK offer?
Nutrient is built on a optimized fork of PDFium — the same engine used by Chromium and Android. We support encrypted PDFs, never persist passwords, and follow strict peer-reviewed development and testing practices.
Our SDK is compatible with major operating systems, including Windows,
macOS, and Linux. We also offer APIs for popular languages such as
JavaScript, Python, and C# to minimize the external dependencies
required, simplifying the integration process.
