How to Use the QR Code Reader
Upload any image containing a QR code and this tool will instantly decode it — right in your browser. No data is sent to any server.
Step-by-Step Instructions
- Upload an image — Drag and drop an image onto the upload area, or click to browse your files. Supported formats include PNG, JPEG, GIF, WebP and BMP.
- Read the result — The decoded QR code content appears immediately. If it's a URL, it will be displayed as a clickable link.
- Copy to clipboard — Click the "Copy" button to copy the decoded text for use elsewhere.
- Scan another code — Click "Clear" to reset and upload a new image.
Tips for Best Results
- Image clarity — Use a well-lit, sharp photo where the QR code is clearly visible and not blurry.
- Minimal cropping — The QR code should include the quiet zone (white border) around it for reliable scanning.
- Straight angle — Photos taken at a straight-on angle decode more reliably than those taken at steep angles.
- Contrast — QR codes with strong contrast between the dark modules and light background scan best.
What Can Be Decoded?
- URLs — Website links and deep links
- Plain text — Notes, messages and other text content
- Contact info — vCard data embedded in QR codes
- WiFi credentials — Network name, password and encryption type
- Email and phone — mailto: and tel: links
Frequently Asked Questions
How does the QR code reader work?
The tool processes your image entirely in the browser using JavaScript. It draws the image to an invisible canvas, reads the pixel data, and runs a QR detection algorithm to find and decode any QR code present. No image data is uploaded to a server.
What image formats are supported?
You can upload PNG, JPEG, GIF, WebP and BMP images. For the best results, use a clear, well-lit photo where the QR code is easy to see.
Why does it say "No QR code found"?
This can happen if the image is blurry, the QR code is too small, partially cropped, or photographed at a steep angle. Try using a clearer, larger image taken straight-on with good lighting.
Is my image data private?
Yes. The entire decoding process runs in your browser. Your image never leaves your device — nothing is uploaded to any server.
Can this read barcodes or other 2D codes?
This tool is designed specifically for QR codes. It does not decode standard 1D barcodes (UPC, EAN, Code 128) or other 2D formats like Data Matrix or Aztec codes.
