If you have a full Creative Cloud or just an Acrobat DC subscription, you’ll be interested to know that Adobe has just launched Adobe Scan. Scan is a free document scanning app (available on iOS or Android) that uses Optical Character Scanning (OCR) to convert text in images into editable text. All you need to do is point your device at a document, the app takes a picture and uploads it to the Document Cloud Servers. When you access the PDF version from any device, you’ll find the text selectable and editable.
On a first test we found the process simplicity itself though the resulting text was subject to some random and missing characters so we recommend making sure your document is positioned completely flat in a well-lit area to minimise conversion errors.
