Is this QR code generator really free?+
Yes, completely free with no signup, no watermarks, no download limits, and no expiration on generated codes. All features including logo embedding, color customization, SVG export, and batch generation are available at no cost. All processing happens in your browser — we don’t store any of your data.
Do QR codes generated here expire?+
No. QR codes generated with this tool are static codes — the data is encoded directly in the image. They will work forever and don’t depend on any external service. As long as the destination URL is active, the QR code will work.
What is the best format to download my QR code?+
For most uses, PNG is the best choice. For print materials like business cards, posters, or packaging, SVG is ideal because it’s a vector format that scales to any size without losing quality. JPEG is smaller in file size but doesn’t support transparency.
Can I add my company logo to the QR code?+
Yes, you can upload any PNG, JPG, or SVG logo and it will be placed in the center of the QR code. The tool automatically increases the error correction level to H (30%) when a logo is added, ensuring the code remains scannable even with the logo covering part of it. We recommend keeping the logo under 25% of the QR code’s area.
How do I create a WiFi QR code?+
Click the WiFi tab, enter your network name (SSID), password, and select your encryption type (WPA/WPA2 is the most common). The tool generates a QR code that, when scanned by a smartphone, will prompt the user to connect to your WiFi network automatically. This works on iPhone (iOS 11+) and Android (10+).
What is error correction and which level should I use?+
Error correction allows QR codes to be read even when partially damaged or obscured. Level L recovers 7% of data, M recovers 15%, Q recovers 25%, and H recovers 30%. Use Level M for most purposes. Use Level H when adding a logo, printing on curved surfaces, or in environments where the code might get dirty or damaged.
How small can I print a QR code?+
The minimum recommended print size is 2cm × 2cm (about 0.8 × 0.8 inches) for a QR code encoding a short URL. More complex codes with more data need to be larger. Always test by scanning from the intended viewing distance before mass printing.
Is my data safe? Do you store anything?+
All QR code generation happens entirely in your browser using JavaScript. No data is sent to any server. We don’t store, log, or transmit any content you enter — including URLs, WiFi passwords, contact information, or uploaded logos. Close the tab and everything is gone.
What’s the maximum amount of data a QR code can hold?+
A single QR code can store up to 4,296 alphanumeric characters or 7,089 numeric characters. However, more data means a more complex (denser) QR code that’s harder to scan. For best results, keep content under 300 characters. For URLs, use a URL shortener if the link is very long.
