Decode text encoded in QR codes
A QR code (Quick Response Code) is a two-dimensional barcode that stores information in a black-and-white grid pattern. Developed by Denso Wave in Japan in 1994, QR codes can be quickly scanned with a smartphone camera to access URLs, text, contact info, and other data.
This tool supports most QR code formats including standard QR codes (Model 1, Model 2) and Micro QR codes. You can upload common image files such as JPG, PNG, GIF, and WebP, or scan directly with a camera. Damaged or partially obscured QR codes can often still be read thanks to error correction.
All QR code decoding is processed within your browser and scanned data is never sent to or stored on any server. Your privacy is protected, so QR codes containing personal information can be scanned with relative confidence. However, always verify URLs contained in QR codes before visiting them.
Yes. You can upload a QR code image file directly or use a screenshot captured from your screen to read QR codes without a camera. The image upload method is especially useful for decoding previously saved QR code images.
The QR code reader is a free online tool that lets you instantly scan QR codes and view their contents using your smartphone or computer camera. Supports various types of QR codes including URLs, text, contacts, and Wi-Fi credentials.
QR codes were invented in 1994 by Masahiro Hara, an engineer at Denso Wave, a Japanese auto parts manufacturer. Short for "Quick Response," QR codes adopted a two-dimensional matrix format to overcome the limitations of traditional barcodes. They are recognized in any scan direction thanks to finder patterns (square markers) located at three corners. QR codes can store up to 7,089 numeric characters or 4,296 alphanumeric characters, and feature error correction that can restore data even if up to 30% is damaged.
QR codes are used widely across many fields — restaurant menus, payment systems, transit card alternatives, marketing campaigns, digital business cards, and product information lookup are all common everyday uses. Since the COVID-19 pandemic, they have become even more prevalent as a contactless service tool.
For successful QR code scanning, keep your camera lens clean and maintain an appropriate distance so the entire QR code fits within the frame. In environments with strong light reflections, adjust the angle to avoid glare. QR codes saved as image files can be scanned using the image upload feature.
