Read Barcode App — Scan & Decode on Any Device
A free, installable read barcode app that runs entirely in your browser. Scan UPC, EAN, QR, Data Matrix and more — offline-capable, private, with nothing to download from an app store.
Install ReadBarcode as an app
Add the read barcode app to your home screen — it opens in its own window, works offline and launches as fast as any installed app.
ReadBarcode is a read barcode app you install straight from the browser. It is the same toolkit every page on this site already runs — a barcode and QR reader, a set of generators, and the GTIN and check-digit validators — packaged as a Progressive Web App so it earns a home-screen icon, opens in its own window and keeps working without a connection.
There is nothing to download from the App Store or Google Play, no account to create and no subscription. Point your camera at a barcode and the read barcode app decodes it on the spot; the camera feed and the scanned value never leave your device.

Frequently asked questions
- Is the read barcode app free?
- Yes. ReadBarcode is completely free — no subscription, no signup, no in-app purchases. You install the same web app every tool on this site already runs in; installing just adds a home-screen icon and offline support.
- Do I need to download it from the App Store or Google Play?
- No. ReadBarcode is a Progressive Web App (PWA), so it installs straight from the browser — there is no app-store listing, no review wait and no separate download. On iOS use Safari's Share menu; on Android Chrome offers an Install prompt; on desktop the address bar shows an install icon.
- Does the read barcode app work offline?
- The browser-based tools do. Once you have opened the app, the barcode reader, QR and barcode generators, and the GTIN / check-digit validators keep working with no connection — decoding and generation run entirely on your device. Lookups against external product databases still need the network.
- Which barcodes can the app scan and read?
- Every common 1D and 2D symbology: UPC-A, UPC-E, EAN-13, EAN-8, Code 128, Code 39, ITF-14, QR Code, Data Matrix, PDF417 and Aztec. Point the camera at a barcode or upload a photo and it decodes automatically.
- Is my camera or scanned data sent anywhere?
- No. The camera stream and every scanned value stay on your device — decoding happens in the browser. There is no account, no server-side storage and no telemetry on what you scan.
- What devices does the read barcode app run on?
- Any device with a modern browser — iPhone and iPad (Safari), Android phones and tablets (Chrome, Edge, Firefox), and Windows / macOS / Linux desktops (Chrome, Edge). The same app installs on all of them.
