Scan QR from Uploaded Image lets you decode QR codes from any image file — screenshots, photos, downloaded images, or scanned documents. Simply upload a picture containing a QR code and the tool extracts the encoded content in seconds. This is especially useful when you have a QR code saved as an image on your device and need to read it without using a live camera scanner.
The tool uses the jsQR library directly in your browser to analyze the image pixel data and detect QR codes. It supports multiple image formats including PNG, JPEG, WebP, GIF, and BMP. If the QR code is not detected on the first attempt, the tool automatically retries with inverted colors to handle negative or stylized QR codes.
Everything is processed entirely on your device. When you select an image file, it is read into memory using the FileReader API, drawn onto a hidden canvas element for pixel analysis, and passed to jsQR for decoding. The original image file and decoded data never leave your browser — no uploads, no server processing, no data storage. This makes the tool completely private and suitable for scanning sensitive or confidential QR codes.
Once decoded, the result is displayed in a clear success card. If the content is a web URL, UPI payment URI, email address, phone number, or other supported link type, an "Open URL" button appears for one-tap navigation in a new tab. You can also copy the result to your clipboard or share it using the native share sheet on supported devices.
