About this app

Turn your phone into a lightning-fast, watermark-free document studio with MintScan: PDF Scanner & OCR — the all-in-one offline PDF scanner, AI text extractor, digital signature studio, and document security vault built for professionals, students, and everyday life.

Unlike traditional scanner apps that hold your documents hostage behind expensive weekly subscriptions, plaster ugly watermarks across your pages, or upload your private files to unknown cloud servers, MintScan processes 100% of your documents locally on your device. No mandatory account sign-up. No cloud snooping. No watermarks.

✨ 8 POWERFUL PDF & SCANNER TOOLS IN ONE APP:

1. 📸 AI-CRISP DOCUMENT & RECEIPT SCANNER
• Digitize paper contracts, tax receipts, invoices, books, and handwritten notes into razor-sharp multi-page PDFs or .JPG images in seconds.
• 4 Studio Optical Filters: Original Color, Magic Pro (shadow removal & contrast boost), High-Contrast B&W Document, and Archival Grayscale.
• 3-Tier Smart File Size Compression: Choose between Email Safe (<300 KB for government & job portals), Standard Balanced, or Archival 300 DPI HD.
• Zero Watermarks: Every PDF and JPG you export is 100% clean and executive-ready.

2. 🔓 PERMANENT PDF PASSWORD UNLOCKER
• Tired of typing a long password every single time you open your monthly bank statement, mobile money statement (M-Pesa), or encrypted payslip?
• Enter the password once in MintScan to strip the lock forever and save a permanently unlocked PDF copy on your phone.
• 100% offline decryption — your confidential financial statements never leave your device.

3. ✍️ DIGITAL FINGER SIGNATURE & OFFICIAL STAMP STUDIO
• Sign PDF contracts, lease agreements, and forms directly on your screen without printing a single sheet of paper.
• Draw smooth, pressure-responsive signatures in 4 executive ink colors (Executive Blue, Carbon Black, Emerald, or Crimson).

4. 🪪 ID CARD FRONT + BACK ON 1 A4 SHEET
• Automatically aligns and centers both the Front and Back of any National ID, Passport, Student ID, or Driver's License onto a single printable A4 page.
• Includes a 1-tap High-Contrast Photocopy B&W mode optimized for laser printers and official KYC bank submissions.

5. 🔍 OFFLINE AI OCR (IMAGE & PDF TO EDITABLE TEXT)
• Powered by on-device Google ML Kit neural text recognition — works with zero internet connection.
• Extract copyable, editable text from camera photos, gallery screenshots, or existing multi-page PDF documents.
• Export extracted text directly to Microsoft Word (.doc), Plain Text (.txt), Searchable PDF, or copy straight to your clipboard.
