No. These are static QR codes that encode data directly. They work as long as the encoded content remains valid. Unlike dynamic QR services, there's no subscription required and they never expire.

You can generate multiple QR codes in batch mode by uploading a TXT file (one URL per line) or CSV file. Generate up to 100 codes at once. For larger batches, process multiple files.

Yes. All QR codes are free for personal and commercial use without attribution required. Use them on products, marketing materials, business cards, or any commercial application.

For print, use at least 2cm x 2cm (about 80px) for reliable scanning. For posters or displays viewed from a distance, use larger sizes (300-1000px). Always test with the actual device and distance before finalizing.

Currently, logo insertion requires image editing software. Generate the QR code here, then use a tool like Canva or Photoshop to overlay your logo in the center. Ensure the logo doesn't cover more than 30% of the code.

QR scanners need contrast to detect patterns. Light-colored QRs on dark backgrounds or low-contrast color combinations may fail. Use dark foreground (blue, black, dark green) on light background (white, light gray) for best results.

Static codes (like ours) encode data directly—they work offline and forever. Dynamic codes redirect through a server, allowing URL changes and scan tracking, but require subscriptions and can expire if not maintained.

Yes, select WiFi mode and enter your network name (SSID), password, and security type (WPA/WPA2). The QR code will instantly connect compatible devices to your network when scanned—great for guest networks.
