Document Reader: PDF Viewer is an all-in-one app for reading and working with documents on your phone. It supports PDF, Word, Excel and PowerPoint files, along with many other formats, so you don’t need to switch between different apps just to open your files. It can also find documents already stored on your device, making it easier to keep everything in one place.

There’s quite a lot you can do beyond reading. You can edit Office files, sign PDFs, merge or split documents, scan paper pages and convert files into different formats. The built-in OCR can recognize text in photos and scans, while the AI assistant can help summarize, translate or answer questions about documents. You can also open files from cloud storage services and share or print them when needed.
