What is a QR Code Debugger?+
A QR Code Debugger lets you upload or paste a QR code image and instantly see what data it encodes, along with technical details like the QR version, module size, encoding mode, finder pattern coordinates, and the raw byte payload.
Is my QR code image uploaded to a server?+
No. The entire decoding process happens in your browser using JavaScript. Your image is never sent to any server. You can verify this by opening your browser's Network tab — no upload requests are made.
What QR code formats are supported?+
Standard QR codes (ISO/IEC 18004) in PNG, JPG, GIF, WebP, and BMP. Supports Numeric, Alphanumeric, Byte (UTF-8), and Kanji encoding modes.
Can I create branded QR codes with a custom logo?+
Yes! Short10 lets you create dynamic QR codes with your own logo, brand colors, and custom short links.
