Free QR Code Generator

Yes, completely free. There are no hidden charges, no subscription fees, and no account required. Generate as many QR codes as you need at no cost.

No. Since we generate static QR codes (the data is encoded directly into the image), they never expire. The QR code will work as long as the destination URL or content is valid. We don't host your QR codes — you download the image file directly.

For most print uses, 800×800px is ideal. For large-format printing (posters, banners), use 1200×1200px. For digital use like websites and emails, 200×200px or 400×400px is sufficient. Always ensure your printed QR code is at least 2×2cm (about 0.8 inches) to be reliably scannable.

Yes! Use the color picker to choose any dark color for your QR code. Ensure sufficient contrast with the background (typically white) — dark navy, black, dark green, or deep purple work well. Avoid light colors or low-contrast combinations as they may not scan reliably.

Yes. We generate PNG images with Level H (High) error correction, which means your QR code remains scannable even if up to 30% of it is obscured or damaged. You can download up to 1200×1200 pixels for crisp, print-ready output.

We don't store or log the content you encode in QR codes. The data is sent to our server only to generate the image, and we immediately return the PNG without persisting your data. For highly sensitive information, consider that QR codes encode data in a readable format.

Simply open your smartphone's camera app and point it at the QR code. Most modern phones (iPhone and Android) will automatically detect the QR code and display a notification or link. Tap the notification to open the encoded content. No special app is needed — your built-in camera handles it.

QR codes are used for a wide range of purposes including sharing website URLs, displaying restaurant menus, sharing digital business cards, connecting to WiFi networks, mobile ticketing, contactless payments, marketing campaigns, and product packaging. They provide a fast, convenient way to bridge the physical and digital worlds.

No. Our generator creates static QR codes, which means the data is permanently encoded into the image. Once generated, the content cannot be changed. If you need to update the encoded information, simply generate a new QR code with the updated content. This is a key advantage of static codes — they work forever without depending on any external service.

A QR code can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. However, the more data you encode, the denser and more complex the QR code becomes, which can make it harder to scan — especially at smaller sizes. For best results, keep your content concise.

For reliable scanning, a printed QR code should be at least 2×2 cm (approximately 0.8×0.8 inches). The ideal size depends on the scanning distance — as a rule of thumb, the QR code should be at least 1/10th of the scanning distance. For example, if someone will scan from 1 meter away, the code should be at least 10 cm wide.
