Free Online QR Code Scanner

Our QR code scanner lets you decode any QR code directly in your browser — no app installation required. Whether you have a screenshot, a saved image, or want to use your device's camera, this tool instantly reads and displays the encoded information.

QR codes (Quick Response codes) are two-dimensional barcodes that store data such as URLs, text, contact information, WiFi credentials, and more. They were first invented in 1994 by Denso Wave for tracking automotive parts and have since become ubiquitous in marketing, payments, authentication, and everyday information sharing.

This scanner uses the jsQR library to perform client-side decoding, meaning your images and camera feed are processed entirely in your browser. No data is sent to any server, ensuring complete privacy and fast results.

Frequently Asked Questions

What types of QR codes can this scanner read?
This scanner can read all standard QR code formats including URLs, plain text, email addresses, phone numbers, WiFi credentials, vCards, and more. It supports QR codes of any size and error correction level.
Is my data safe when using this scanner?
Yes, absolutely. All QR code processing happens entirely in your browser using JavaScript. No images or decoded data are uploaded to any server. Your privacy is fully protected.
Why can't the scanner read my QR code?
Make sure the QR code image is clear and not blurry. The QR code should be well-lit and not at an extreme angle. Try cropping the image to focus on just the QR code. Damaged or partially obscured QR codes may not be readable.
Does the camera scanner work on mobile devices?

What image formats are supported for upload?
You can upload images in PNG, JPEG, GIF, BMP, and WebP formats. The scanner works best with clear, high-contrast images where the QR code is prominently visible.

Yes, completely free with no limits, no signup, and no watermarks. Generate unlimited QR codes for personal or commercial use.

Can I customize the QR code appearance?

What size should I download the QR code?

For print, use at least 300 DPI at your target physical size. For screens, 200x200 pixels is sufficient for most uses. Larger sizes give better scan reliability from a distance.

Do QR codes expire?

Static QR codes (like these) never expire. The data is encoded directly in the pattern and doesn't depend on any server or service. They work forever as long as the image is intact.

Are my QR codes stored on your server?

No. QR codes are generated entirely in your browser using JavaScript. Nothing is uploaded or stored. Your data remains completely private on your device.
