How do I generate a QR code online for free?

Enter text, a URL or Wi-Fi details, choose size and color, then download a PNG QR code with no sign-up.

Can I make a downloadable high-resolution QR code image?

Yes, export your QR code as a PNG at the resolution you need for print or web.

Does generating a QR code upload my data anywhere?

No. It is generated entirely in your browser and stays on your device.

QR codes without a middleman

Most QR tools render or read your code on their server — which means they see exactly what the code contains, and often stamp their logo or tracking onto it. This tool does both directions entirely in your browser: generation uses the open-source qrcodejs library, decoding uses jsQR. Your content and images never leave the page.

Create any kind of QR code

Links — websites, menus, event pages.
Wi-Fi access — use the format WIFI:T:WPA;S:NetworkName;P:password;; and phones join with one scan.
vCards & plain text — contact details, notes, anything under ~2,000 characters.

Make it yours

Pick a built-in style — Classic, Ocean, Sunset, Forest or Midnight — upload your own background image, fine-tune the dot and background colors, and drop a logo in the center. The code automatically switches to high error correction when a logo is present, so it keeps scanning reliably.

Read a QR code from an image or URL

Paste the direct address of any image that contains a QR code, or drop in a screenshot or photo. The decoder reads it straight off your device and shows the underlying text — handy for recovering links, Wi-Fi passwords or vCards you can't otherwise copy.

Frequently asked questions

Will generated codes scan at small sizes? Keep the contrast high and avoid busy colors; 300 px is plenty for screen display, use 800 px for print.
Can I put my own logo in it? Yes — upload an image and it's placed in the center on a small pad. The code automatically switches to high error correction so it still scans reliably with the logo in place.
Will my code scan with a custom background image? Yes, as long as contrast is strong: keep light images with dark dots (or dark images with light dots) and avoid busy detail behind the modules. The built-in styles are tuned for this already.
Why can't it read some image URLs? The browser only lets a page read pixels from an image if that image's server allows cross-origin access. If a URL fails, download the image and upload it instead — uploads always work.
Is there a character limit? QR version 40 holds about 2,953 bytes of text — far more than any typical use.
