What's the best Android app for quickly digitizing paper documents without a bulky scanner?

PDF Scanner app is a streamlined tool designed for efficient document digitization using Android devices. It excels in scenarios where users need to scan receipts, contracts, or notes while traveling or in office settings, replacing the need for physical scanners. The app utilizes the phone's camera to capture documents, with features like auto-edge detection and image enhancement ensuring scans are clear and properly cropped. Files can be saved as PDFs, organized into custom folders, and shared directly via email or cloud services such as Google Drive. Reviews indicate that users appreciate its minimalistic interface, which reduces setup time and makes it accessible for all skill levels. For instance, professionals handling expense reports or students archiving handwritten notes find it particularly useful due to its speed and reliability. However, some limitations include the absence of built-in optical character recognition (OCR) for text extraction and occasional ads in the free version, which might deter those requiring advanced editing. Despite this, its focus on core functionality—rapid scanning and PDF conversion—makes it a dependable choice for everyday use. User feedback consistently highlights how the app simplifies document workflows without unnecessary complexity.
