QR Code Scanner / Reader

🔒 In your browser

Upload an image to read what a QR code contains — decoded in your browser.

How it works

Upload a photo or screenshot containing a QR code and read what it contains — a link, WiFi credentials, contact card, and more. Runs entirely in your browser.

🖼️Choose an image with a QR code

🔒 The image is decoded locally with the Web Crypto/Canvas APIs — nothing is uploaded.

🔒 Generated in your browser: the data you encode — WiFi passwords, contacts, payment details — is rendered locally and never uploaded. Downloads have no watermark and no signup. Remember a QR is not encryption: anyone who scans it sees the data.

About the QR Code Scanner / Reader

This free online QR code scanner reads a QR code from an image you already have — a photo, a screenshot, or a downloaded picture — and shows you exactly what it contains: a website link, Wi-Fi details, a contact card, plain text and more. It's handy when a code appears on your own screen and you can't point a camera at it.

Decoding happens entirely in your browser using the canvas and jsQR — your image is never uploaded, so it's private by design.

How to scan a QR code from an image

Take a screenshot of the QR code, or save the image to your device.
Click 'Choose an image' and select that file.
The decoded content appears instantly. If it's a link, you get a one-click 'Open link'.

When to use an image scanner instead of a camera

The QR code is on the same screen you're using (an email, a PDF, a web page).
You received the code as an image in chat and want to check where it leads before tapping.
You're on a desktop or laptop without a camera.

Frequently asked questions

Can I scan a QR code from a screenshot?

Yes. That's exactly what this tool is for — upload a screenshot or any saved image containing a QR code and it decodes the content, which is useful when the code is on the same device you're using.

Does it use my camera?

No. This scanner reads a still image you upload. It's ideal for codes already on your screen or in your files. For live scanning of a physical code, your phone's camera app usually works best.

Why does it say 'No QR code found'?

The image may be blurry, too small, low-contrast, or the code may be partly cut off. Try a clearer, closer, well-lit image where the whole QR code is visible and square-on.

Is my image uploaded when I scan it?

No. The image is decoded locally in your browser with JavaScript. It never leaves your device and isn't sent to any server.

🔗 Embed this tool on your website — free

Copy this and paste it into your page's HTML. The tool runs in the visitor's browser, just like here. Change height to fit, or add the optional auto-resize snippet below. Add ?theme=dark to the URL for dark mode.

<iframe src="https://toolhq.dev/embed/qr-code-scanner/" title="QR Code Scanner / Reader — ToolsHub" width="100%" height="520" style="border:1px solid #e5e7eb;border-radius:12px;max-width:680px" loading="lazy"></iframe>

Optional: auto-resize the iframe height

Add this once on the same page so the iframe grows to fit the tool:

<script>
addEventListener("message", function (e) {
  if (e.data && e.data.type === "toolshub:resize") {
    document.querySelectorAll('iframe[src*="/embed/"]').forEach(function (f) {
      if (f.contentWindow === e.source) f.style.height = e.data.height + "px";
    });
  }
});
</script>
