FAQ
Common questions
How do I generate a WiFi QR that works on iPhone and Android?
Use the WiFi template and make sure SSID/password are exact (case-sensitive). If you have special characters like ; : , or \, regenerate and test scan on both devices. Read the WiFi format guide →
What QR size should I print (business card / menu / poster)?
For business cards, start at 20–25mm. Keep a quiet zone (blank margin) and avoid low contrast. See the sizing guide →
Which download format is best: SVG or PNG?
Use SVG for print (sharp at any size). Use PNG for quick sharing. SVG vs PNG →
How do I make a “merchant QR” (menu / support / review)?
Use the URL QR code generator for menus, review links, coupons, and any website destination. For support chat, use WhatsApp Business (or WhatsApp). If the destination might change later, use Dynamic QR (redirect) so you can update the link without reprinting. Browse templates →
