Efficient document upload apps offer additional valuable features like document organization, sharing, search capabilities, and collaboration features. Thus, these apps enable businesses to reduce paper clutter and manage documents more efficiently.

To upload a hard copy of a document, you first need to digitize it.

Digitize and upload documents using a camera

One of the quickest ways to digitize your documents without spending any extra money is to use the camera of your mobile device, such as an Android device. You can take a picture of your document with your smartphone’s camera, then upload the image using a document upload app and store it in cloud storage.

For example, you can use the Filestack file uploader service to upload your files quickly using a beautiful drag-and-drop interface and store them on a remote server.

Moreover, the uploader also supports file previews and multiple file uploads.

Digitize and upload documents using a scanner


A scanner is a device that enables users to convert a hard copy of their documents into digital information. To do this, you need to place the paper documents on the scanner bed and start the scanning process. The scanner then processes the documents and converts them into digital formats, such as PDF or image files. You can then upload those files from your computer to a remote server using an upload document application.

However, nowadays, smartphones have built-in scanner apps that allow you to scan your documents using your smartphone camera instead of buying a scanner device separately.
