Free QR Code Scanner
Scan with your camera or upload an image. No app, no sign-up — decoded entirely in your browser.
Decoded entirely in your browser — the image never leaves your device.
How to scan a QR code online
Point your camera at a QR code, or upload a photo that has one in it — this tool reads the code and shows you exactly what it contains before you act on it. It works the same as a phone's native camera scanner, but from any browser, with no app to install.
Tap Use Camera and allow camera access when your browser asks. Hold the QR code steady inside the frame — most codes decode in under a second once they're in focus. No camera, or permission blocked? Switch to Upload Image and choose a photo instead; a screenshot, a downloaded image, or a picture you took earlier all work the same way.
Everything happens in your browser. The video frame or uploaded image is decoded locally using JavaScript — it is never uploaded to QRPulse or any other server. That also means it works without an internet connection once the page has loaded, and nothing about what you scan is logged anywhere.
Why scan here instead of a random app
Nothing leaves your device
Decoding happens locally in your browser. No image or camera frame is ever sent to a server.
No app to install
Works instantly in any modern browser — nothing to download, no permissions beyond the camera itself.
Works from a saved photo
Already have a screenshot or picture of the code? Upload it instead of pointing a live camera.
Any device, any browser
iPhone, Android, or desktop with a webcam — no OS-specific app required.
Scanning a code safely
A QR code is just data — a link, a bit of text, Wi-Fi details. Decoding one can't run anything on its own. The actual risk shows up after you decode it, the same as clicking any link: if the result is a website address, glance at the domain before opening it, the same way you'd check a link in a text message from an unknown sender.
This scanner shows you the full decoded content — the destination URL, the Wi-Fi network name, the contact details — before you tap anything, so you're never opening a link blind.
QR Code Scanner — FAQ
It uses your browser's camera access to read frames from your device camera, or lets you upload a saved image — either way, the QR code is decoded directly in JavaScript running in your browser. No app install, and no image or camera frame is ever sent to a server.
Scanning itself is safe — decoding a QR code only extracts the text or link it contains, it cannot run code on its own. The actual risk is what you do after: if the decoded content is a link, check the domain before opening it, the same way you'd check any unfamiliar URL. This tool shows you the decoded content before you open anything.
No. Both the camera feed and any image you upload are processed entirely on your device using your browser's built-in canvas and JavaScript — nothing is sent to QRPulse's servers or anywhere else.
Yes — switch to the "Upload Image" tab and choose a photo from your camera roll or files. It works the same as scanning live, just decoding a still image instead of a camera feed.
Any standard QR code — website links, Wi-Fi network credentials, contact cards (vCard), plain text, email addresses, phone numbers, and SMS messages. The tool detects which type it is and labels the result accordingly.
Most likely your browser is blocking camera permission — check your browser's site settings and allow camera access for this page, then reload. If you're on a laptop without a camera, or the permission prompt doesn't appear, use the "Upload Image" tab instead.
Yes, in any modern mobile browser (Safari, Chrome) that supports camera access, plus desktop browsers with a webcam. If a device's browser blocks camera access entirely, image upload still works everywhere.
Yes, with no sign-up, no limit on how many codes you scan, and no watermark or ad on the result. It's a client-side tool — there's no per-scan server cost to recoup.
