With the great camera that comes built into iOS devices these days, it's really quick and easy to get a great quality "scan" of a document right from your device without a physical scanner or computer. There are many apps in the app store that will help with this, but I've found Readdle's Scanner Pro to be the best.
Documents can be scanned using the camera and taking new pictures from the app, or using images from your camera roll. All documents are output in PDF, and the app will natively upload to WebDav, Dropbox, Evernote, and Google Drive. It will also open the document into any app that accepts PDF files. There is a sync with iCloud to keep all of your iOS devices in sync. It will email or AirPrint a scanned document, and will even fax your document around the world for a small fee, which is paid via In-App Purchase using your iTunes account.
The app does a great job of walking the user through scanning a document, but here's a quick rundown of the process to scan a document using the camera from the app:
- Place your document on a mostly solid-color surface. I would recommend not putting it under direct light, and using a darker surface for documents on white paper.
- Inside Scanner Pro tap the Camera+ image in the bottom middle of the screen. Use the blue shutter button with the white camera to snap a photo. Try to keep the device as parallel to the document as possible. Don't try to align the document with the edges of the camera, this will be compensated for on the next screen. You can also use the flash if necessary; toggle for the flash is in the top left corner.
- Once you've snapped your picture, the next screen will allow you to adjust the edges of the document using the blue dots at each of the four corners. I found that the app does a pretty good job of finding the document edges on it's own if you follow my recommendations from step 1.
- The next screen allows the adjustment of brightness, paper size selection, rotation of images, and color type selection (color, black & white, or grayscale).
- Tap Save and you now have a scanned document. You can change the name of the document using the Edit button in the top right corner of the screen. If you need to add additional pages, use the camera+ and image+ buttons at the bottom center.
- Use the two outter buttons on the bottom of the screen to share/save your document.
This app works with iPhone, iPad, and iPod Touch running iOS 6.0 or later.
