Download Adobe Scan from either the Google Play Store or Apple App Store. It is free to use and available for iOS and Android devices. This app allows you to scan documents with your cell phone and convert them into a PDF format. Open the app and either log in to your existing Adobe account or create a new account if needed. Allow the app to access your camera. Make sure your phone is parallel to the document that you are scanning and that all four corners of the document are visible. If your document has multiple pages, continue to take pictures of each needed page before saving it as a PDF. When you have all the pages you need, click on the picture on the bottom right of your app with the blue number in the corner. On the top right of the next screen, you can click the little pencil icon, rename your document if you like and then click “OK”. To save your pictures as a PDF, click “Save PDF” also at the top right of that same screen. On the next screen, you can either send the PDF you just created by clicking on the “Share” link next to the document you just created, or at the bottom right, you can click on the camera icon to create another document. The documents that you create will stay in this app so if you need to find them later, just open the app, click on the little house at the top right of your screen, and there they all are.
