PDF Scany

Getting started with the app is relatively simple. You can either photograph a document directly or use a photograph taken earlier. Conversion into PDF is relatively quick, and you have some options available in terms of what gets scanned (you can crop the document to a required size, for instance). You can even use a batch-scan mode to shoot several documents in a row. Finally, you can password-protect the files and upload them to a storage service. PDFs are smaller than photos, making this app a real space-saver.
