Smart PDF Reader & Viewer is a fast, simple, and easy-to-use PDF Reader app for Android. It helps you open PDF files, read documents, organize important PDFs, and manage files from folders you choose.

Many users receive PDF files on WhatsApp, download documents from Chrome, save tickets, bills, school notes, bank statements, office files, resumes, and certificates. Over time, these PDF files can be scattered across different folders. Smart PDF Reader & Viewer helps you build a clean PDF library from selected folders such as Downloads, Documents, WhatsApp Documents, or other folders that contain your PDF files.

The app uses Android’s secure folder picker. You choose the folders you want the app to access, and the app scans PDF files from those selected folders only. Your PDF files stay on your device.
