Barcode Scanner reads CODE128, EAN, UPC, CODE39, ITF, and Codabar barcodes from either an uploaded photo or your device's live camera.
Blurry, low-contrast, or heavily angled photos are harder to decode. Try a sharper, more head-on shot with good lighting, or use the live camera mode, which can try multiple frames as you adjust the angle.
No. Both the uploaded image and the live camera feed are analyzed entirely in your browser. Nothing is recorded or sent to a server.
