Microsoft is constantly adding lesser-known apps to Office. One of the best ones is the mobile app Office Lens, which lets you snap pictures of paper documents and convert them into digital documents. Thanks to a recent update, you can now take photos of multiple pages and merge them into a single document.
From Android Police:
The changelog only has one new item on it: “Our top requested feature is here. Scan more than one image and save them all as single PDF, a Word or PowerPoint file on OneDrive, or simply export them as images to the same OneNote location.” Office Lens includes multiple capture modes, like whiteboard and business card. This affects how the app will process the image. What’s new this time is that after capturing an image, you can hit the “plus” button to take another.
