ACE Scanner - PDF Scanner App

Turn paper documents into PDFs

ACE Scanner - PDF Scanner App uses an Android phone camera to scan receipts, notes, business cards and other documents. It detects page edges, crops the image and applies processing options such as black-and-white or photo mode to make the result easier to read. Scans can be saved as PDF files, making the app useful for students, office workers, small businesses and anyone who needs a digital copy without a desktop scanner.

Tools for working with documents

The app goes beyond capturing a page. Its OCR tool can recognise text in a scan so you can copy, search or edit the written content. You can also read and organise PDF files, rename them, search your document collection and adjust the structure of a file by adding, removing or rearranging pages. Page layouts can be set to common paper sizes, including A4 and Legal.

Sharing, signatures and protection

ACE Scanner includes tools for signing documents electronically and adding watermarks. These options suit forms, agreements and work documents that need a signature or a visible ownership mark before they are shared. The app is therefore a practical fit for occasional paperwork as well as regular document handling.
