Scan · Convert · Share

A native Android app that converts images into professional PDF documents - no internet, no bloat, no BS.

💡Why I Built This

I was tired of scanning assignment sheets with third-party apps that shove ads in your face, upload your files to some random server, or lock basic features behind a paywall. All I wanted was: take photo → get PDF. That's it.

So I built Scanify a clean, offline, zero-dependency scanner that does exactly that. No accounts. No cloud. No nonsense. Just your images turned into a proper PDF, saved locally, ready to share wherever you want.

This is also my first real Android project beyond tutorials, and it's still actively being built. I'm learning a lot along the way the PdfDocument API, RecyclerView touch mechanics, scoped storage changes across API levels, and what it actually takes to go from a working prototype to something polished. The core flow works; the rest is being shaped as I go.

🔍 What It Does

Select images from your gallery or capture them live with the camera. Arrange them in any order using drag-and-drop. Generate a properly scaled A4 PDF. Share it anywhere WhatsApp, Gmail, Drive, Teams, you name it.

That's the whole flow. No sign-in. Fully offline.

✨ Features

Image Input

• Import multiple images from the device gallery
• Capture directly via camera
• Fast image loading with native Android APIs

Pre-Conversion Controls

• Grid preview of all selected images before conversion
• Drag-and-drop page reordering via ItemTouchHelper
• Long-press to remove individual images

PDF Generation

• Powered by Android's native PdfDocument API - zero external PDF libraries
• Automatic A4 scaling and page alignment
• Runs entirely on-device; no network calls, no uploads

Output & Sharing

• Custom filename before saving
• Saved to device storage via MediaStore API
• Share to Gmail, WhatsApp, Telegram, Google Drive, Microsoft Teams, or any compatible app via FileProvider

⚙️ Tech Stack

Layer	Technology	Role
Language	Java	Core application logic
UI	XML + Material Design Components	Layouts and interface
List	RecyclerView + GridLayoutManager	Image preview grid
Reordering	ItemTouchHelper	Drag-and-drop page ordering
PDF Engine	PdfDocument API	Native PDF generation
File Sharing	FileProvider	Secure URI-based file sharing
Storage	MediaStore API	Writing PDFs to device storage

Everything here is stock Android - no third-party PDF libraries, no image-processing SDKs. Part of the challenge was figuring out how much you can do with just the platform.

🔐 Permissions

The app requests only what it actually needs, and respects Android's evolving storage permission model across API levels.

Permission	Target	Purpose
CAMERA	All versions	Capture images directly in-app
READ_MEDIA_IMAGES	Android 13+	Gallery access (scoped)
READ_EXTERNAL_STORAGE	Android ≤ 12	Gallery access
WRITE_EXTERNAL_STORAGE	Android ≤ 9	Save PDF to external storage

🚀 Getting Started

Clone the repo

git clone https://github.com/Sanchet237/Scanify.git

Open in Android Studio

1. Launch Android Studio (Hedgehog or newer)
2. Go to File → Open and select the cloned directory
3. Wait for Gradle sync to finish
4. Hit Run on an emulator or physical device (API 21+)

Requirements

• Android Studio Hedgehog+
• Android SDK 21+
• Java 8+

🎯 Current Status & Roadmap

Scanify is under active development. The core pipeline — select, arrange, convert, share — is functional. Everything below is what's being worked on or planned next.

In Progress

• Stabilizing edge cases in image scaling across different aspect ratios
• Improving the result screen UX

Planned

• Dark Mode (the UI is begging for it)
• OCR Text Recognition (make PDFs searchable)
• PDF Compression (useful for large photo sets)
• PDF Password Protection
• Merge / Split PDFs
• Watermark Support
• Cloud Backup integration
• Multi-language Support

This list will evolve as the project grows. If you have ideas or spot a bug, feel free to open an issue — feedback during active development is genuinely useful.
