Everything works just as it does if you initiated scanning from the device, including the Auto/Manual switch and the need to tap Save when you’re done. However, instead of saving the document to Files, it will appear as a new document in Preview, where you can work with it like any other PDF and save it to your drive.
Final Thoughts
There are two caveats to scanning documents using your iPhone or iPad:
● This approach to scanning does not do optical character recognition (OCR) to make the scanned text selectable—the resulting PDF pages are just images. Online tools can perform OCR on a PDF; we’ve seen good results from AvePDF’s OCR PDF tool. This might not be a good idea with sensitive documents.
● Scanned documents tend to be large. If your scan ends up too big to share via email, for instance, other online PDF compression tools can shrink files. If you use AvePDF to OCR your document, another click on its Hyper-Compress PDFs tool can compress the same document by as much as 90%.
Overall, you’ll probably get better quality from a hardware scanner—particularly a flatbed—because it’s easier to position the pages perfectly, the light is stronger and more even, and there’s no need to deskew (straighten) the scanned page images, as Apple’s software attempts to do when you’re not directly over the page. But it’s hard to beat the convenience of a quick scan with your iPhone when quality isn’t paramount.
