How to scan a saved QR image
Open the scanner, select Scan image, and choose a PNG, JPEG, WebP, GIF, or BMP file. You can also drag the file into the page or paste a screenshot from your clipboard. Keep the complete QR code visible for the most reliable result.
Why local scanning matters
A QR image can contain private information, such as a Wi-Fi password, contact card, or internal URL. QR Scan Online performs the decoding in your browser, so the image does not need to leave your device.
Improve a difficult scan
Crop away unnecessary background while keeping the full code and its white border. Use a higher-resolution image, correct strong perspective distortion, and avoid reflections. If the code is inside a PDF, capture a clear screenshot of that page first.
QR image decoding happens inside your browser. QR Scan Online does not need a copy of the image or the decoded content.
