Privacy First: Your files are processed securely. Whenever possible, processing happens in your browser and files are never stored on our servers.

Decode barcodes and QR codes from any image using the browser's native BarcodeDetector API (Chrome 83+, Edge 83+). Upload a JPEG, PNG, WebP, GIF, or BMP image by dropping it onto the upload zone, clicking to browse, or pasting from clipboard (Ctrl+V). The detector scans for all supported formats simultaneously: QR Code, Code 128, Code 39, Code 93, EAN-13, EAN-8, UPC-A, UPC-E, ITF, PDF417, Aztec, Data Matrix, and Codabar. Multiple barcodes in a single image are all detected and listed. Results show the decoded value and format name. URLs are shown as clickable links. Copy any result with one click. All processing happens locally in your browser - images never leave your device. Requires Chrome or Edge; Firefox and Safari are not yet supported.
