Store description excerpt
DocMaster is an on-device document and file toolkit for Android. Your files never leave your phone — no account, no analytics, no cloud. FILE MANAGER • Browse your whole device storage as one tree — sort, show hidden files, refresh • Multi-select with breadcrumbs; copy, move, rename and delete with a paste bar • Recents and Favorites that follow your files when you move or rename them FIND ANY FILE • A device-wide catalogue of your documents, built on-device • Browse by type — PDF, Word, Excel, PowerPoint, images and more • Fast name search across everything PDF TOOLS • Merge several PDFs into one • Split or extract a page range • Rotate, compress and add a text watermark • Password-protect (encrypt) a PDF, or stamp a signature image • Share and print SCAN & OCR (on-device) • Scan documents with the camera — edge detection, multi-page, save to PDF • Scan ID cards • Extract text from images with on-device OCR (Latin and Devanagari scripts) • Select text right on the image, like a lens — long-press and drag to pick words, then copy, translate, search or share VIEW DOCUMENTS • Read PDFs with scroll, zoom, search, bookmarks and a thumbnail grid • Open Word, Excel and PowerPoint content in-app (a content-accurate view of text and data, not a full layout renderer) • View images with pinch-to-zoom CONVERT • Images to PDF, and PDF pages to images • Convert and compress images • Extract a PDF's text into a Word (.docx) file MORE TOOLS • QR scanner and QR code generator • Calculator and unit converter • Storage analyser and duplicate-file finder PRIVATE BY DESIGN • Your files, scans, photos and recognised text stay on your device — never uploaded. No account, no analytics, no cloud sync. • OCR, document scanning and translation all run on-device. • Only two optional, tap-to-use actions reach the internet: "Search the web" opens your browser with the text you picked, and on-device Translate downloads a language pack once from Google (the pack — never your text), then works offline. 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.
