A free app for iPhone, by Readdle Inc..
This is an all-in-one scanner app that lets you quickly and easily scan paper documents and convert them into PDFs or JPEGs.
With the Scanner Mini app, you can scan anything: receipts, IDs, books, business cards, notes, photos, emails, and more.
And once you’re done scanning, you can immediately convert your documents into PDFs or JPEGs, which you can save and share with just a couple of clicks.
This is a really easy-to-use app, so you don’t have to worry about complex instructions or any other technical issues. Just choose your document, tap the Scan button, and you’re done!
You can also draw or write on your scans to add additional notes. And if you want to make organizing even easier, you can create a document by selecting a category, so you can create a separate document for every type of document you have.
