• Live preview and instant validation. The generated code updates as the user types in the input field. The application automatically validates data for specific formats like EAN, ensuring the generated codes are functional and meet required standards before being saved.
• Support for multiple formats. In addition to standard QR codes, the tool allows generating specialized formats such as EAN-13, EAN-8, and Code 128. These formats are widely used in retail and inventory management environments, ensuring compatibility with commercial scanning systems.
• Smart content templates. Built-in forms are included for easily generating complex QR content. It supports configurations for WiFi networks, contact cards (vCard), geolocation coordinates, calendar events, and direct links to WhatsApp and Telegram.
• Advanced QR customization. Users can adjust technical parameters such as the error correction level (from Low to High) to maintain code readability even if it is partially damaged. It is also possible to remove white margins or enable transparent backgrounds for professional integration into graphic designs.
• Integrated decoder. The application functions as a code reader. It allows dragging and dropping existing images or opening files from the disk to instantly decode the information stored in QR and barcodes.
• Clipboard and design export. The generated images can be copied directly to the system clipboard for immediate use in external editors. They can also be saved as high-quality PNG files, with the option to set custom dimensions in pixels.
• Portability and cross-platform. Being a Java-based utility, it does not require an installation process. The executable file can be carried and run on Windows, macOS, and Linux systems without additional configurations.
• Numeric code generation. The interface includes dedicated fields for creating EAN codes. The system verifies the length of the entered digits and automatically applies the check digit calculation algorithm to ensure the validity of the generated barcode.
• Contact data management. The vCard module allows entering structured data such as full name, company, phone, email, and address. The application compiles this information into a QR code that can be scanned and saved directly to a mobile device's address book.
• WiFi connectivity setup. The network function allows generating QR codes with wireless authentication parameters. Users can specify the network SSID, encryption type, and password so that mobile devices connect automatically when scanning the code.

The development of QR Code Studio was initiated in 2025 by a team of independent developers with the goal of creating a unified desktop tool for barcode manipulation. The application is written entirely in the Java programming language, ensuring its cross-platform nature and execution without complex external dependencies.
