Common Mistakes to Avoid
Image Quality Issues:

Technical Considerations:

Security Awareness:
- Suspicious Links: Always verify URLs before clicking, especially from unknown sources. QR codes can contain malicious links.

Frequently Asked Questions
What image formats does the QR code decoder support?
Our QR code decoder supports all major image formats including JPG, JPEG, PNG, GIF, and WebP. The tool can process images of various sizes and resolutions, though higher quality images generally produce better results.
Are my uploaded images stored on your servers?
No, your privacy is our priority. All image processing happens locally in your web browser using client-side JavaScript. Images are never uploaded to our servers or stored anywhere. Once you close or refresh the page, all data is completely removed.
What types of content can QR codes contain?
QR codes can contain various types of data including website URLs, plain text, contact information (vCard), WiFi credentials, email addresses, phone numbers, SMS messages, calendar events, and geographic coordinates. Our decoder automatically identifies and displays the content type.
Why is my QR code not being recognized?
Common reasons include: poor image quality or resolution, insufficient lighting or contrast, partial QR code visibility, damaged or corrupted QR code, or non-standard QR code format. Try capturing a clearer image with better lighting and ensure the entire QR code is visible.
Can I decode QR codes from screenshots?
Yes, absolutely! Our tool works perfectly with screenshots from phones, computers, or tablets. Simply save the screenshot and upload it to our decoder. This is particularly useful for QR codes received via email, social media, or messaging apps.
Is there a limit to how many QR codes I can decode?
No, there are no limits! You can decode as many QR codes as you need, completely free of charge. Our tool is designed to handle multiple decoding sessions without any restrictions or usage caps.
What should I do if the decoded content looks suspicious?
Always exercise caution with decoded content, especially URLs from unknown sources. Verify the legitimacy of websites before visiting them, and never enter personal information on suspicious sites. If a QR code contains contact information or other data, verify its authenticity before using it.
Can the tool decode multiple QR codes in one image?
Our current decoder processes one QR code per image and will detect the first clear QR code it finds. If you have an image with multiple QR codes, we recommend cropping the image to show only the QR code you want to decode for best results.
Does the QR code decoder work on mobile devices?
Yes! Our QR code decoder is fully responsive and works excellently on smartphones and tablets. You can upload images from your device's photo gallery or take a new photo directly through your mobile browser to decode QR codes on the go.
What happens if I upload a very large image file?
While our tool can handle large image files, processing time may increase with file size. For optimal performance, we recommend using images under 10MB. The tool automatically optimizes images during processing to ensure efficient decoding without compromising quality.
