QR & Barcode Studio is the high-performance offline QR code generator, 1D barcode maker, and smart scanner for Android. Customize with logos, gradients, and custom eyes—backed by real-time Scannability Radar contrast verification.
Everything you need to craft high-impact QR codes, generate industry-standard barcodes, and scan barcodes rapidly—without touching the cloud.
Embed custom logos with transparent cutouts, apply dual-color linear gradients, choose from square, rounded, dot, or leaf module styles, and customize outer and inner corner eye shapes.
Never print an unreadable QR code again. The built-in Scannability Radar analyzes WCAG contrast ratios, error correction capacity, and payload density in real time before you export.
Generate crisp retail and industrial 1D barcodes including Code 128, EAN-13, UPC-A, and Code 39 with configurable bar color, background color, dimensions, and text captions.
Export clean PNG images up to 4096×4096 pixels, infinite-resolution SVG vectors for signage and graphic design, or centered print-ready PDF documents for instant distribution.
Scan QR codes and all standard 1D barcodes from your camera or gallery with sub-second detection, flashlight support, pinch-to-zoom, and continuous batch scanning for rapid inventory capture.
Fast, unified local database for both generated and scanned items. Instant real-time search, category filtering chips, directional tabs, favorites pinning, and single-tap re-exporting.
Captured directly on Android — showcasing the styling engine, export sheet, scanner, and unified history.
Structured for rapid user understanding and search engine snippet extraction.
Open QR & Barcode Studio, choose your payload type, and enter your data. Tap the Style button, navigate to the Logo tab, and select an image from your gallery. Pick an inner clip shape—circle or rounded square—and adjust the logo size. The real-time Scannability Radar ensures your code remains instantly readable.
Select Wi-Fi from the generator category chips. Enter your network SSID, select your encryption security type (WPA/WPA2/WPA3, WEP, or Open), and input the network password. Check the hidden network box if applicable. The app immediately encodes a standardized Wi-Fi string that any modern smartphone camera can scan to connect without typing passwords.
Yes, QR & Barcode Studio is completely free to use with zero hidden subscriptions, in-app purchases, or advertisements. All features—including logo embedding, color gradients, vector SVG/PDF exports, batch scanning, and 1D barcode generation—are unrestricted out of the box. No account sign-up or credit card is required.
Yes. QR & Barcode Studio functions 100% offline with zero internet permissions requested in its Android manifest. QR code generation, camera scanning, barcode rendering, and history logging execute entirely on your device using local processing. Your camera frames and generated codes are never transmitted to external servers or cloud analytics.
Traditional 1D barcodes (like UPC, EAN-13, and Code 128) store alphanumeric data horizontally in parallel lines and hold up to 20-30 characters. 2D QR codes store information both vertically and horizontally in a grid, holding over 4,000 characters with built-in Reed-Solomon error correction for links, contacts, Wi-Fi credentials, and rich text.
QR & Barcode Studio is a proprietary, privacy-first 100% offline QR code generator, 1D barcode maker, and smart scanner for Android. Built with Flutter, it features logo embedding, gradient styling, customizable eye modules, real-time scannability verification, high-resolution vector exports (SVG, PDF, PNG up to 4096px), and local Hive database storage with zero internet permissions, cloud telemetry, or third-party ads.
