Digital storage is increasingly popular, making it easier to store and retrieve important documents, and allowing people to cut down on paper storage such as filling cabinets.
iPhones and Macs have a number of in-built features that enable document scanning, such as Notes and Files apps, while there are also external third-party apps from Google Drive to Dropbox that can help.
Scanning documents enable them to be saved as PDFs and shared with other people via messaging or email, or exported to other apps for editing.
Documents can be saved in colour or as black and white, and there are also options to adjust the borders of scans and add further pages.
