Open and view any PDF document with lightning-fast rendering, smooth scrolling, pinch-to-zoom, and instant page navigation—even on large, multi-page files. Proview works seamlessly as your default PDF viewer, letting you open PDFs directly from Gmail, WhatsApp, Google Drive, and your device file manager.

Paper receipts, invoices, and bills

Business contracts, forms, and agreements
