Whether you’re designing for business, branding, or personal use, QR Studio gives you full control over how your QR codes look and function. The app is divided into three main tabs: Create Tab: The Create tab offers a wide range of customization options for generating QR codes. Users can adjust visual elements such as eye shape and color, data shape and color, and choose the desired error correction level. Additional settings include control over QR structure (gapless or standard), position, size, and rotation. The app also supports background customization, including color and border properties like radius, color, style, and width. Text can be added with flexible styling options—covering decoration, color, font style, weight, alignment, position, and rotation.

History Tab: Access a complete history of all the QR codes you’ve created or scanned. This makes it easy to revisit, reuse, or share previous designs and scans. QR Studio is built for designers, developers, marketers, and everyday users who want complete freedom in how they create and manage QR codes.
