ScanMaster Pro – Doc Scanner, PDF Editor & Converter
Turn your phone into a powerful doc scanner and PDF editor. ScanMaster Pro lets you scan, convert, sign, merge, compress, and lock PDF files — all offline, with no subscription and no limits on how many documents you create.
Every scan, OCR job, and edit happens locally on your device. Your files are never uploaded to a server, so your private documents, IDs, and contracts stay fully secure.
Doc Scanner & PDF Converter
Scan receipts, invoices, IDs, notes, or textbook pages with automatic edge detection and smart contrast enhancement for sharp, print-ready results. Convert photos (JPG, PNG, WebP) or plain text files into PDF documents individually or in batches.
OCR Text Scanner
Built-in optical character recognition turns handwritten or printed pages into editable, searchable text you can copy or export instantly.
Merge, Split & Organize PDFs
Combine multiple PDFs into one file, split large documents into separate pages, delete duplicates, rotate misaligned pages, and drag-and-drop to reorder — all in a few taps.
Compress PDF Files
Reduce PDF file size without losing readability, so large documents are easier to email, message, or store.
Sign PDF Documents
Draw a digital signature once and apply it to contracts, agreements, or invoices anytime — resize and reposition as needed.
Lock & Unlock PDFs
Add password protection to keep sensitive files private, or unlock documents you've already secured.
Crop & Resize Images
Adjust photos to exact pixel dimensions and compression levels before converting or sharing.
Auto-Find PDFs on Your Device
ScanMaster Pro automatically detects existing PDFs in your downloads folder, with search, sorting, and list or grid views for quick access.
Built for freelancers and business owners managing contracts, students digitizing notes and textbooks, travelers storing tickets and passport copies, and accountants tracking receipts and expense reports.
Download ScanMaster Pro and carry a complete doc scanner, PDF converter, and editor in your pocket — fast, private, and free of subscriptions.
