What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode that stores information — URLs, plain text, contact details, Wi-Fi credentials, and more. When scanned with a phone camera, it instantly opens the encoded content. QR codes are widely used on menus, posters, packaging, business cards, and tickets. Our generator creates them entirely in your browser, so nothing you encode is ever sent to a server.
Why Use Our Free QR Code Generator?
- 100% Private: The QR code is generated locally in your browser. Whatever you type never leaves your device — safe for sensitive links.
- No Watermark: The downloaded PNG is clean. No logos, no branding, no ads embedded in your QR code.
- Customizable: Choose from four sizes, four error correction levels, and any foreground/background color.
- Instant Preview: The QR code updates in real time as you type — no clicking "generate" repeatedly.
- Free Forever: No signup, no limits, no subscription. The tool is sustained through non-intrusive ads on the page.
Understanding Error Correction
QR codes use Reed-Solomon error correction, which means a damaged or partially obscured code can still scan. Higher levels add redundant data so the code tolerates more damage — but make it denser. Low (7%) is fine for clean digital display; High (30%) is best for printed codes that may get scratched or dirty, or when you want to overlay a small logo in the center.
Common Use Cases
- Website links: Put a QR code on a poster or flyer that opens your site.
- Wi-Fi sharing: Encode your network name and password so guests can connect by scanning.
- Contact info: Share a vCard so people can save your details with one scan.
- Menus & labels: Restaurant menus, product labels, and event tickets.
- App downloads: Direct mobile users to the right app store.
Frequently Asked Questions
Is this QR code generator really free?
Yes, completely free with no limits. We sustain the tool through non-intrusive advertising on the page.
Is my data uploaded to a server?
No. The QR code is generated entirely in your browser using JavaScript. Whatever you type stays on your device.
What format is the download?
PNG. The image is high-resolution (up to 768×768) with a transparent-friendly background you can customize.
Do the QR codes expire?
No. A QR code is just an image encoding your text — it never expires and works forever, as long as the content behind a URL stays online.
Can I add a logo in the center?
Direct logo overlay isn't built in, but if you set error correction to High, a standard QR scanner can still read the code with a small logo placed manually on top of the downloaded PNG.
Is there a scan limit?
No. Since the QR code simply encodes text, it can be scanned unlimited times. There's no tracking or analytics behind it.
Does it work on mobile?
Yes! The generator works on iOS, Android, and any modern mobile browser.
