QR Code Error Correction Levels

Higher error correction lets a QR code remain scannable even when partially obscured or damaged, at the cost of a denser (larger) code.

Level Recovery En İyisi Trade-off
L (Düşük) 7% Temiz dijital ekranlar Smallest QR code
M (Medium) 15% General purpose, printed materials Dengeli
Q (Çeyreklik) 25% Outdoor signage, curved surfaces Larger code
H (High) 30% Logo kaplamaları, hasarlı/kirli koşullar Largest code

Sıkça Sorulan Sorular

Ne tür QR kodları oluşturabilirim?

You can create QR codes for URLs and websites, plain text, WiFi network credentials, vCard contact information, and email addresses. Each type has a specialized input form that formats the data correctly so scanners open the right app automatically.

Can I customize the colors of my QR code?

Yes! You can set custom foreground and background colors using our color pickers. Make sure there is enough contrast between the two colors for reliable scanning. Dark foregrounds on light backgrounds work best, and we recommend avoiding very light foreground colors.

What is error correction level?

Error correction allows a QR code to be scanned even if partially damaged or obscured. Level L recovers 7%, M recovers 15%, Q recovers 25%, and H recovers 30% of data. Higher levels increase the QR code's density but make it more resilient, which is useful when printing on textured surfaces or adding a logo overlay.

What download formats are available?

You can download your QR code as a PNG image (raster format, great for web and print) or as an SVG file (vector format, perfect for scaling to any size without quality loss). SVG is ideal for large format printing like posters or banners where the code needs to stay sharp at any scale.

Is this QR code generator free?

Yes, our QR code generator is completely free with no limits on how many codes you create. All QR codes are generated in your browser with no watermarks, no sign-up required, and no restrictions on commercial or personal usage.

Are my QR codes generated privately?

Yes. All QR code generation happens entirely in your browser using JavaScript. No data is sent to our servers, so your WiFi passwords, contact details, and URLs remain completely private. This makes the tool safe for encoding sensitive information.

How do I create a QR code for WiFi so guests can connect instantly?

Select the WiFi QR type, then enter your network name (SSID), password, and encryption type (WPA/WPA2 or WEP). When guests scan the generated code with their phone camera, they connect automatically without typing the password. This is popular for restaurants, offices, and home networks.

What is the best size for printing a QR code?

As a general rule, a QR code should be at least 2 cm x 2 cm (about 0.8 inches) for close-range scanning such as business cards or menus. For posters or signs scanned from a distance, increase the size proportionally. Download the SVG format for print to ensure crisp edges at any dimension.

Do the QR codes I generate expire?

No. The QR codes generated here are static, meaning the data is encoded directly into the pattern and never expires. As long as the encoded URL or content remains valid, the QR code will continue to work indefinitely with no ongoing fees or subscriptions.

Can I add a logo or image to the center of my QR code?

Oluşturucumuz şu anda gömülü logoları desteklemiyor, ancak herhangi bir görüntü düzenleyiciyi kullanarak küçük bir logoyu manuel olarak kaplayabilirsiniz. Oluşturmadan önce hata düzeltme düzeyini H (%30) olarak ayarlayın; bu, logonuzun kapladığı küçük bir merkezi alanla bile kodun taranabilir kalması için yeterli yedeklilik sağlar.
