 # How to render PDF pages using PDFium on Android?
 
-The Syncfusion Flutter PDF Viewer allows users to render PDF pages using the PDFium library on Android through an optional package, [syncfusion_pdfviewer_android](https://pub.dev/packages/syncfusion_pdfviewer_android). This enables loading password-protected documents and rendering PDF pages with better performance on Android devices running API levels below 35. By default, the PDF Viewer uses the [PdfRenderer](https://developer.android.com/reference/android/graphics/pdf/PdfRenderer) to render PDF pages on the Android platform.

 However, the `PdfRenderer` does not support loading password-protected documents on Android devices running API levels below 35. To load password-protected documents on Android, we decrypt the PDF document using the `syncfusion_flutter_pdf` library and employ the decrypted bytes to load the PDF document.
