Know more about Fill’s document scanner app

A document scanner is an electronic device that can scan and convert paper documents into digitized formats. However, the term is no longer limited to traditional office or business scanners. It could also refer to mobile apps, software, or browser-based tools.

Document scanner apps can turn any mobile device into a portable scanner. Once installed, it will use the device’s native camera to create a scanned image of the physical document. These types of apps also vary in terms of features and functionality.

However, scanning a document using a smartphone may result in low-quality scans, with text that appears too bright or blurry. You can improve the overall scan quality by:

  • placing the document on a flat surface
  • adjusting the contrast and brightness
  • choosing a black and white filter instead of grayscale

When choosing a scanner app, make sure that it’s capable of producing high-quality scans. Otherwise, you’ll have to repeat the scanning process until you get the results you need.

Yes, you can use your mobile phone or tablet as a document scanner. Some devices like the iPhone already have a built-in document scanning tool. To scan a document with an iPhone, you need to go to the Notes app and create a new note. From there, you’ll see an option to scan documents. Don’t worry; the process is similar to taking a photo.

If your phone doesn’t have this functionality, all you need to do is to install a scanner app. The app will let you use your phone’s default camera to take a snapshot of any document and convert it into a digitized format. The result will be similar to scanning using a traditional office scanner but with the option to scan from anywhere.

With a document scanner app, it’s easy to create digitized copies of any printed material, including business cards and receipts.
