A4 Polaroid Collage Generator
The A4 Polaroid Collage Generator is a Python-based desktop application that takes already-created Polaroid-style images and automatically arranges them into a 2×3 grid (6 Polaroids) on a standard A4 sheet for printing. The workflow is simple: first, create Polaroid-style images using the mobile app — [ Instaroid – Polaroid Maker ] — then import those images into my software, which automatically aligns and positions them perfectly. Instead of manually resizing and arranging in Canva or Photoshop, the tool exports a ready-to-print A4 JPEG collage with a single click — Upload Polaroids → Auto Arrange → Export A4 JPEG → Print & Frame.
Features
- Upload 6 Polaroid photos (exported from the Instaroid app)
- Automatically arranges them into a 2×3 A4 grid
- One-click high-quality A4 JPEG export
- Simple and clean desktop GUI (Tkinter-based)
- No photo editor required — fully automated
Components Used
- Python — Core development language
- Tkinter GUI — User interface for selecting images and exporting output
- PIL / Pillow Library — Image processing, resizing, and collage generation
- OS library — Handles file access and saving
How it Works
- Use the Instaroid / SimplePiece app to create square Polaroid images.
- Open the A4 Polaroid Collage Generator.
- Click Select and Combine Images
- Select the 6 Polaroid images.
- Software automatically arranges them on A4 and exports a JPEG.
- From phone → Polaroid app → Desktop → A4 collage → Print
Working
Upload 6 Polaroid photos (exported from the Instaroid app)
Select and Combine Images
Upload 6 images from your system.
The program will automatically arrange them in a 2×3 grid.
The final A4-sized JPEG will be saved and ready for printing.
