DocMaster PDF Reader & Scanner

DocMaster is a PDF reader, document scanner and file manager in one free app. Read PDF files, scan documents to PDF, convert images to PDF (JPG to PDF), merge, split and compress PDFs, and open Word, Excel and PowerPoint files — all on your phone. Your documents never leave your device. No account, no cloud sync; free and ad-supported.

See the privacy policy. Note: DocMaster requests "All files access" so it can work as a real file manager across your whole storage. You can decline — it then falls back to the system folder picker for opening individual documents.
