مولد رمز QR

A QR (Quick Response) code is a two-dimensional barcode that stores data like URLs, text, or contact information. Scanning with a smartphone camera instantly opens the encoded content.

You can encode: website URLs, plain text, email addresses, phone numbers, WiFi credentials, contact cards (vCards), SMS messages, and more. URLs are the most common use.

Larger sizes (300-500px) are better for print materials. Smaller sizes (100-200px) work for digital use. The minimum readable size depends on scanning distance and the amount of data encoded.

Yes! You can choose both the QR code color (foreground) and background color. Ensure high contrast between colors for reliable scanning—dark codes on light backgrounds work best.

Common issues: insufficient contrast between colors, code is too small, image is blurry, or the data is corrupted. Try using higher contrast colors (black on white) and larger size.

QR codes can store up to ~3000 alphanumeric characters or ~4300 numbers. For longer URLs, consider using a URL shortener before generating the code.

QR codes are saved as PNG images with transparency support. This format works well for both digital use and printing.

Yes! QR codes generated here are free for personal and commercial use. There's no watermark or attribution required.

Static QR codes (like ours) never expire—they permanently encode the data. However, if you encode a URL that later becomes invalid, the code will still scan but lead nowhere.

Most smartphones can scan QR codes using the default camera app. Simply point your camera at the code and tap the link that appears. Test before printing or distributing!
