PDF Scanner is a free app for scanning documents to PDF files via the device camera. The app is perfect for any sort of document, like personal identification and finance reports. Documents with multiple pages can be scanned a page at a time and then easily combined within the app. Edges are automatically detected and perspective is adjusted by the software in a snap. Additionally, if more than one page is scanned on the camera simultaneously, the software is equipped with intelligent page recognition functionality that will attempt to automatically separate the pages. Scanned documents can then be easily shared via Bluetooth, email or Google Drive. Documents can also be scanned as simple JPEG images. Other options are available, such as scanning to black and white or grayscale, paper size settings and contrast and brightness modifications.

The software is a product of KaiKaiSoft and is on its second major revision. It requires Android operating system 5.0 and up, making it incompatible with many older devices. The software supports the English and Vietnamese languages.
