Converting paper documents into digital formats means you’ve got backups of your paperwork should you ever need them. It can also help you clear out a substantial amount of clutter from your home or office — perhaps a whole filing cabinet’s worth.

It’s now easier than ever to scan documents using today’s phones — a large flatbed scanner is no longer needed as it was in the past. Receipts, business cards, bills, and any other kind of printed material can be stored digitally.

If you’ve got an iPhone, you can do this straight from the built-in Notes or Files apps. If those don’t quite give you the features you need, there are third-party alternatives that will do the job as well.

The process of scanning a document is similar in both Notes and Files. To get started in Notes, open or create a note, then tap the paperclip icon at the bottom, then Scan Documents. In Files, tap the three dots (top right), then Scan Documents.

This gets you into the scanning interface. By default, you’ll be in auto mode — frame the document in the camera viewfinder, and when it’s lined up, a picture is automatically taken. Line up the next page, and after a moment, another capture is made.

Tap Auto (top right) to switch to manual mode, which lets you take each snap using the shutter button manually. The Auto button changes to read Manual, and you can tap it again to switch back to automatic mode.

You’ll see a couple of icons at the top. The lightning bolt lets you control the flash, while the three circles lets you switch between Color, Grayscale, Black & White, and Photo for the scanning mode.

When all the documents and pages have been captured, tap Save. In Notes, the pages you’ve scanned are then added to the current note, and in Files the pages are saved together as a PDF file (you may be asked where you want to save your file).

Apple’s Continuity suite of features includes a useful little trick that lets you scan documents from your Mac using an iPhone. As with other Continuity features, you must be signed in to the same Apple account on both devices for this to work, and both devices need to have Wi-Fi and Bluetooth turned on.

This works in Finder, Mail, Messages, Notes, Keynote, Numbers, Pages, and TextEdit on macOS. There are three options, depending on the app you’re in:

All three methods will launch the document scanner on your iPhone — at which point you’re back to the interface we covered in the previous section. When you tap Save on your iPhone, the documents show up in your Mac app.

The process in iOS and macOS is very straightforward, but plenty of other apps do document scanning too, if you need them. A couple that I use regularly are Google Drive and Dropbox, so you might find they suit you better if those apps are where you tend to keep your digital archives.

With Google Drive, tap the scan document icon in the lower right corner (it looks like a page with a frame around it). This takes you to a camera interface that matches the one you get in Notes and Files, but when you tap Save, you get to choose where in your Google Drive you want the scanned PDF uploaded to.

You get a few more options with Dropbox: Tap the blue + (plus) button at the bottom, then Scan files. There’s the Auto and Manual toggle switch again, but as soon as a page is captured, you get taken to a new screen where you can edit the borders of the scan or rotate it, and add further pages. When that’s sorted, you’re able to choose where in your Dropbox you want the scanned PDF to be saved, and how much compression to apply.
