Scan any QR code to instantly reveal its hidden details, including error correction level, version, model, mask pattern, module size, and bit stream. You can also recreate the original QR code as a clean PNG or SVG with the exact same module layout—even from blurry or compressed images.

Hi everyone! 👋 I'm excited to share QR Code / Barcode - Scan App, a QR parser and analyzer that helps you inspect what's actually inside QR codes. Most scanner apps only show the decoded text. I wanted a tool that could also display technical information such as the error correction level, version, mask pattern, module count, and even the underlying bit stream. It can also regenerate a clean PNG or SVG with the exact same module layout from a scanned QR code. I originally built it for my own learning and debugging, but I hope it will also be useful for developers, designers, QA engineers, and anyone who works with QR codes. I'd love to hear your thoughts, suggestions, or feature requests. Thanks for checking it out!
