Frequently asked questions
You can generate QR codes for URLs and websites, plain text, email addresses, phone numbers, SMS messages, WhatsApp messages, and WiFi network credentials. Each type is optimized for its specific use case so the QR code works correctly when scanned by any standard smartphone camera.
Yes, all QR codes generated on WorldMerch are completely free with no restrictions. You can use them for personal or commercial purposes — on business cards, flyers, packaging, menus, presentations, or anywhere else. There are no watermarks and no usage fees.
QR codes generated here are static and never expire. The data is encoded directly into the QR code image itself, so it will always work as long as the destination (such as a website URL) remains active. Since we do not store or host your QR codes on our servers, there is no expiration date tied to our service.
Yes. You can customize both the foreground (dots) color and the background color of your QR code to match your brand or design. Keep in mind that for reliable scanning, there should be strong contrast between the foreground and background colors. Avoid using very similar shades or inverting the colors (dark background with light foreground may not scan reliably on all devices).
PNG is the recommended format for most uses — it is universally supported and works well for digital and print use. SVG is ideal if you need a scalable vector format that can be resized to any dimension without losing quality, which is especially useful for large-format printing like banners or posters.
Select the "WiFi" option, then enter your network name (SSID), password, and security type (WPA/WPA2 is most common). Generate and download the QR code. When someone scans it with their smartphone camera, they will be prompted to join your WiFi network automatically — no typing required. This is perfect for homes, cafés, hotels, and offices.
Yes. QR codes are generated entirely in your browser using the QRCode.js library. The data you enter — whether it is a URL, WiFi password, or phone number — is never sent to any server. It stays on your device and is encoded directly into the QR code image locally.
For business cards, a minimum of 2 × 2 cm (about 0.8 × 0.8 inches) is recommended. For flyers and posters, 3–5 cm works well. The larger the print, the easier it is for cameras to scan. Always test your printed QR code by scanning it from the expected reading distance before mass printing.
