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.
