Frequently Asked Questions
How do I scan a QR code online?
Upload an image file containing a QR code (PNG, JPG, WebP, GIF, or BMP) by dragging it into the upload area or clicking to browse. The scanner instantly decodes the QR code and displays its content — no app, no registration, no camera required.
Can I scan a QR code from a screenshot?
Yes. Screenshots work perfectly with this scanner. Take a screenshot of the QR code, then upload it using the upload area. The scanner reads the QR code from the screenshot image just like any other image file.
Can I read a QR code from an image on my computer?
Yes. Save the image to your computer, then upload it to the scanner. The entire decoding process runs in your browser — the image never leaves your device. This is ideal for decoding QR codes received in emails, messages, or downloaded from the web.
Is it safe to scan QR codes online?
Yes, when using a browser-based scanner like this one. All processing happens locally in your browser — your images are never uploaded to any server. However, always verify the decoded URL before clicking it, as QR codes can contain links to phishing sites. This scanner shows you the full content before you open it.
What types of QR codes can be decoded?
This scanner decodes all standard QR code types: URLs (website links), plain text, WiFi credentials (network name and password), vCard contact information, email addresses, phone numbers, SMS messages, calendar events, and geographic coordinates.
Do I need to install an app to scan a QR code?
No. This QR code scanner runs entirely in your web browser. Open this page on any device — phone, tablet, or computer — upload an image, and get the result instantly. No app download, no installation, no registration required.
Can I scan a QR code from a PDF?
Not directly. QR codes inside PDFs need to be extracted first. Take a screenshot of the QR code area in the PDF, then upload the screenshot to the scanner. On most operating systems, you can take a screenshot with Print Screen (Windows), Cmd+Shift+4 (Mac), or the screenshot shortcut on your phone.
Why is my QR code not scanning?
Common reasons: the image is too blurry or low-resolution, the QR code is partially cropped or obscured, poor lighting in a photo, or the image is too small. Try using a clearer, higher-resolution image. Make sure the entire QR code including the white margin (quiet zone) is visible in the image.
Can I scan a QR code without a camera?
Yes. This scanner works from image files only — no camera needed. Upload any saved image, screenshot, or photo containing a QR code, and the scanner decodes it instantly. This is perfect for desktop computers or when your camera is unavailable.
What does a QR code contain?
A QR code can contain various types of data: a website URL, plain text, WiFi network credentials, contact information (vCard), an email address, a phone number, an SMS message, a calendar event, or geographic coordinates. This scanner identifies the type and displays the content accordingly.
