User Interface Customization in Our MAUI PDF Viewer

PSPDFKit for MAUI offers PDF viewer user interface (UI) customization through APIs. These robust APIs for configuring behavior and appearance let you hide or add buttons, change the theme to match your look and feel, trigger workflows, create overlays, and much more.

Using Web APIs

UI customization APIs for the MAUI viewer are identical to those for our Web viewer. When customizing the UI for your MAUI application, refer to the PSPDFKit for Web UI documentation, which is linked below. If you’d like to bridge these APIs with your MAUI app, use our guide that explains how to bridge web APIs.

These APIs will be translated to native APIs in subsequent releases, so stay tuned for updates.
