CamScanner turns your mobile into a portable scanner. Simply snap a photo of a document you want to scan, and the app will automatically crop and enhance the image, making text easily readable. The app also lets you perform OCR (optical character recognition) on your scanned documents to lift out important bits like prices, dates, titles, and details. You can also put customized watermark on your scans, and annotate them with notes and highlighting.
There is also a batch mode to scan multiple documents in a row, and organize them later. You have an option to share your scans with others as a PDF file or high-resolution image. Then you can also create your user account if you wish to sync your scanned documents across all your devices and access them online at CamScanner’s website (www.camscanner.com). You’ll get 200MB cloud storage for free. And yes, the app also lets you scan QR codes.
The app’s free version is more than enough for your basic scanning requirements, but you can also go for premium version via in-app purchases to get extra cloud storage (up to 10 GB), extract texts in scans for later editing and sharing (OCR), password protect the document while sharing it, create one document of multiple scanned pages, auto upload scans to third-party cloud services, and remove ads.
