Question 1

How do I read a QR Code from an image?

Accepted Answer

Upload an image containing a QR Code — the tool reads it and extracts the hidden text or URL. Supports JPG, PNG, WEBP. Can read up to 4,296 alphanumeric characters.

Question 2

Can I scan QR Codes with my camera?

Accepted Answer

Yes! Switch to camera mode and point your camera at any QR Code. It works on both mobile and desktop devices. The QR Code will be decoded automatically.

Question 3

Is QR Code scanning safe?

Accepted Answer

Adwatak reads the QR Code locally in your browser — nothing is sent to any server. However, be cautious about the links you scan. QR Codes are just storage — the destination could be harmful. We show you the content first for safety.

Question 4

What's the difference between QR Scanner and QR Reader?

Accepted Answer

No practical difference. Both decode QR Codes. QR Reader = reads uploaded images. QR Scanner = uses live camera. Both do the same thing. Some apps auto-open links — we show you the content first.

Question 5

Can I read damaged QR Codes?

Accepted Answer

QR Codes have built-in error correction (up to 30%). Smudged, scratched, or partially damaged codes can still be read. Higher resolution images give better results. Completely destroyed codes cannot be recovered.

Question 6

What QR Code types does this support?

Accepted Answer

All standard types: plain text, URLs, Wi-Fi (SSID + Password), vCard contacts, SMS, email, phone numbers, geo-location data, and app store links.

Question 7

Is this tool free?

Accepted Answer

Yes, 100% free with no registration required. Everything happens in your browser — images are processed locally without uploading to any server. Fast, private, and simple.

Question 8

What print quality is needed for QR Codes?

Accepted Answer

Print at 300 DPI minimum. Minimum size: 2×2 cm (0.8×0.8 inches). Test scanning from the expected viewing distance. Use high contrast (black on white) for best results.

Question 9

Can QR Codes store video or images?

Accepted Answer

No, QR Codes store text only. However, they can store a URL link to a video or image. Max storage: ~3 KB. For simple URLs and text, this is more than enough.

Question 10

QR Codes vs NFC — what's the future?

Accepted Answer

QR needs no special chip (every phone camera reads them), is cheaper to print, and easier to distribute. NFC is faster and requires a tap. Both will coexist — QR for print/advertising, NFC for payments.
