 | `Height` | `string` | The PdfViewer height as a [CSS length value](slug:common-features/dimensions). If not set, the component will expand vertically, based on the loaded file. `Height` is required for the component paging and scrolling to work. |
 | `MaxZoom` | `decimal` <br /> (`4m`) | The largest possible zoom level. The default value allows zooming in 4 times (400%). |
 | `MinZoom` | `decimal` <br /> (`0.5m`) | The smallest possible zoom level. The default value allows zooming out to 50%. |
+| `RenderScale` | `double` <br /> (`3.0`) | The resolution of the rendered PDF document. A higher value increases the quality, but also increases the memory consumption. Use a smaller value for large documents or less powerful user devices like mobile phones. |
 | `Width` | `string` | The PdfViewer width as a [CSS length value](slug:common-features/dimensions). If not set, the component will expand horizontally to fill its parent. |
 | `Zoom` | `decimal` <br /> (`1.25m`) | The current zoom level. Use the parameter with two-way binding or with a [`ZoomChanged` event handler](slug:pdfviewer-events#zoomchanged). |
 | `ZoomRate` | `decimal` <br /> (`0.25m`) | The zoom level change that is used by the zoom in and zoom out buttons. |
