Two ways to scan a QR code
This online scanner gives you a choice. Tap Scan with camera to open a live view and point your device at a code, or use Upload image to scan a screenshot or photo you already have. Both paths decode the code on your device and show exactly what it holds, whether that is a website link, plain text, contact details, or Wi-Fi credentials. When the result is a web address, an Open link button appears so you can visit it in one click.
Everything runs locally in the browser, so camera frames and uploaded pictures never leave your device. That makes it safe to scan codes that carry sensitive information, and it means you can scan as many as you want for free without creating an account.
Why scan on a computer
Phone cameras handle most everyday scans, but a browser scanner is handy when the code lives on the same screen you are using. You can scan a code from a PDF, an email, a web page, or a design file without reaching for your phone. It is also useful for checking your own codes: scan a proof before you print to confirm it points where it should.
Create and track your own QR codes
Once you know how easy scanning is, you can put it to work. CodesQR makes dynamic QR codes whose destination you can change anytime without reprinting, plus scan tracking so you can see how many people scanned each code and when. Point a code at a link, a PDF, or any file you upload.

Frequently asked questions
How do I scan a QR code online?
Click Scan with camera to read a code live, or upload an image of the code. The scanner decodes it in your browser and shows the link or text it contains. You do not need to install anything.
Do I need an app to scan a QR code?
No. This scanner runs in your web browser. On a phone you can also open the built-in camera app, point it at a QR code, and tap the notification that appears. Either way, no separate app is required.
Does the camera scanner work on iPhone and Android?
Yes, on modern browsers that allow camera access over a secure (https) connection. When prompted, allow the camera permission. If the camera is unavailable, upload a photo of the code instead and it will still be decoded.
Is scanning private?
Yes. The scan is processed on your own device. Camera frames and uploaded images are read locally and never sent to a server.
The scanner cannot read my code. What should I do?
Hold the code steady and fill the frame, with good lighting and no glare. If the live camera struggles, take a clear photo and upload it. Damaged, blurry, or very low contrast codes can be hard to read.
