Free Online QR Code Scanner

Yes, QRLynx's Online QR Code Scanner is completely free to use for both personal and commercial purposes. There are no scan limits, no hidden fees, and no account registration required to use the basic scanning features.

No app installation is required. Open the scanner in a supported browser, allow camera access for live scanning, or upload a saved image. Availability depends on the device and browser.

Camera and image decoding run in your browser. The tool does not upload the video feed or image file to QRLynx for decoding. Check the decoded URL before opening an unfamiliar destination.

The scanner shows the text encoded in supported QR codes, including URLs, WiFi payloads, vCards, email, SMS, and plain text. It can also read common 1D barcodes when the browser decoder supports the format. It does not look up product prices.

Camera access might be blocked. Please ensure you've clicked 'Allow' when the browser asked for permission. On iOS/Android: Go to Settings > Privacy > Camera and check your browser permissions. On Desktop: Check the lock icon in the address bar to manage site permissions.

Yes! Switch to the 'Upload Image' tab on the scanner. You can upload any screenshot, photo, or saved image file (PNG, JPG, WEBP, BMP). Our advanced algorithm will locate and decode the code even if it's slightly blurry or angled.

The scanner keeps up to 50 recent results in your browser's localStorage so you can copy them again. This history is stored on the device, not in a QRLynx account. You can delete individual entries or clear the list in Recent Scans. Clearing browser site data also removes the local history.

If the scanner is struggling, try these troubleshooting tips: Move your camera closer or further away to find focus. Ensure there is sufficient lighting on the QR code. Clean your camera lens. If uploading an image, try cropping it to just the QR code area.

Yes. If the WiFi QR uses a text payload such as WIFI:T:WPA;S:NetworkName;P:Password;;, the scanner displays that raw text. You can copy it, inspect the fields, and connect through your device settings. Do not share the payload if it contains a private password.

WIFI:T:WPA;S:NetworkName;P:Password;H:false;; is one commonly used WiFi QR text payload. T indicates a security type, S the network name, P a password, and H a hidden-network flag. QRLynx shows the raw payload rather than separate parsed fields. ISO/IEC 18004 specifies the QR symbol and encoding, not a required WiFi payload syntax.

Scan the vCard QR code or upload a saved image to view and copy the encoded contact text. Use your contacts app's supported import workflow to save the contact.

Yes. Upload a screenshot or photo and the scanner displays the decoded URL without opening it. Check the full destination and its spelling before choosing Open Link, particularly for a code on a public surface.

Scan an event QR to view and copy its encoded calendar text, such as a BEGIN:VEVENT payload. Use a compatible calendar app's import workflow to add supported event data.

QR codes store data, often a link. Risks come from acting on harmful destinations or content, including phishing pages, malicious downloads and pre-filled SMS or email scams. QRLynx lets you preview the decoded URL or text before acting. Check physical codes for stickers covering the original. Enter login or payment details only when you expected the request and have verified the genuine website domain or official app. If unsure, open the service directly through a trusted address or its official app, and confirm the recipient before paying.

Your phone's camera or code scanner is convenient for printed codes. Use QRLynx when you want to upload a saved image, view the raw payload before opening a URL, copy WiFi/vCard/event text, or scan from a desktop browser. Windows Camera also supports QR scanning on devices with a camera.

The printed text near a QR code is just a label. It's not encoded in the QR. A common quishing tactic is to print 'menu.example.com' next to a QR code that actually points at a different domain. Always trust what the scanner decodes, not what's printed alongside the code. If they don't match, the code may have been replaced (a sticker placed over the legitimate QR is the most common physical attack).

Yes, in supported mobile browsers. Camera access requires permission and compatible hardware; you can also upload a saved image. Browser and device behavior can vary.

The browser decoder may read common UPC or EAN barcodes. QRLynx displays the decoded number for you to copy.

A static QR contains its fixed payload in the symbol. A dynamic QR usually contains a short URL that redirects to a destination the owner can update. The scanner displays the encoded text of either type when it can decode the symbol.

BarcodeDetector is an experimental browser API that may be available on some devices. QRLynx uses html5-qrcode for camera and image scans and a jsQR fallback for difficult image scans. Available formats and decoding speed depend on your browser, camera, and image quality; the scan runs in your browser.

Yes. Copy a screenshot or image containing a QR code, then press Ctrl+V (Cmd+V on Mac) on the scanner page while focus is outside a form field. The scanner attempts to decode it and saves successful results in local history. No file dialog is needed.

Yes. If the browser exposes more than one camera after permission is granted, a Switch Camera button appears. Use it to choose another available camera without leaving the scanner page.

Yes, on devices that support the MediaTrack torch capability, primarily Android Chrome and Edge on the rear camera. When supported, a Flashlight button appears next to the Switch Camera button while scanning; tap to toggle. iOS Safari does not currently expose the torch API to web pages, so iPhone users won't see the button. The torch is turned off automatically when you stop scanning or leave the page.
