Scanner Mini takes an image of a document, finds the borders of the page, and then crops it. The result is a PDF document without ads or watermarks that can be copied to any PC or Mac via a USB cable. Documents can also be archived through iCloud.
To share the documents directly from your iOS device, you must upgrade to Scanner Pro, which is priced at $6.99.
Using this, you can share documents via email, Dropbox, Evernote, and Google Drive. Additionally, you can print the documents through AirPrint.
Scanner Pro is also fully integrated with the $9.99 PDF Expert app. This app can help you annotate and sign the documents that have just been scanned.
