Generate and decode high-capacity, colourful JAB Codes that hold 3× more data than QR codes. If you can think of it, you can encode it. JABCode Studio transforms digital files into vibrant, scannable colour barcodes for bringing your games, websites, or documents to life on paper. It’s the ultimate tool for creators who want to merge the digital and physical worlds. What is a JAB Code? A JAB Code (Just Another Barcode) is a next-generation, full-colour, open-source barcode standard that can store complex files far beyond the limits of traditional black-and-white QR codes. Each code can hold text, images, apps, or other media — and can even be chained together to represent entire songs, games, web pages, or archives. Why Jabcode Studio? Instead of storing your work on servers or downloads, JABCode Studio lets you print it. Distribute apps, music, or game data through collectible cards, zines, or art prints — all scannable and self-contained.
