About QR Code Reader
QR Code Reader extracts the information stored in a QR code from an image. Upload a screenshot, photo or saved QR image and Zavilo shows the decoded text or URL.
Common use cases
Inspect saved QR images
Open a downloaded image, product graphic or document screenshot and view the QR payload as text.
Verify a generated code
Read back a QR image before publishing it to confirm that the expected URL or text was encoded.
How it works
1
The browser decodes the selected image into pixels.
2
The QR detector searches for the code's finder patterns and reconstructs its data modules.
3
The decoded payload is shown as text and can be opened when it is a supported web URL.
Privacy & file handling
QR detection runs in your browser
The selected image is analyzed locally for QR patterns rather than uploaded to Zavilo for decoding.
Limitations and important notes
- Heavy blur, glare, perspective distortion or a cropped quiet zone can prevent detection.
- A QR code can contain an unsafe or misleading URL; inspect the destination before opening unfamiliar links.
- Very small QR codes may need a higher-resolution source image.
What helps QR recognition?
| Feature | Better | Worse |
|---|---|---|
| Framing | Full code with quiet border visible | Edges cropped off |
| Image quality | Sharp and high contrast | Blurred, reflective or noisy |
| Perspective | Mostly square to the camera | Strongly skewed |
How to use QR Code Reader
- 1
Choose a JPG, PNG or WebP image containing a QR code.
- 2
Wait for the QR code to be detected.

Tips for better results
- Use a sharp image where the full QR code and its white border are visible.
- Avoid strong perspective distortion, reflections or heavy blur.
- If detection fails, crop the image closer to the QR code and try again.
