QR Code Guides — Print, Privacy, WiFi, Reviews & Social
Tutorials written for people who actually print and share QR codes — cafés, hosts, freelancers, and local businesses. Each guide explains when a format fits, how to generate it privately in the browser with maintool, how to print it so it scans, and how to avoid common failures. Generation stays on your device; maintool does not upload WiFi passwords or contact fields to create the image. Jump to a tool anytime: [[URL generator|/]], [[WiFi generator|/wifi-qr-code-generator]], [[WhatsApp generator|/whatsapp-qr-code-generator]], [[Google review QR|/google-review-qr-code-generator]], or [[vCard generator|/vcard-qr-code-generator]].
