# Persistent QR Code Generators ## Overview When you need to create a QR code that will last forever without expiring or requiring a paid subscription, there are several free services that generate **static QR codes**. Unlike dynamic QR codes (which require ongoing service and can expire), static QR codes embed the URL directly into the image itself. ## Key Concept: Static vs Dynamic QR Codes **Static QR Codes:** - URL is permanently encoded in the QR code image - Will work forever, even if the service that created it shuts down - Cannot be edited after creation - No tracking or analytics - **Free and permanent** **Dynamic QR Codes:** - Use a shortened redirect URL (e.g., `qr.io/abc123`) - Can be edited to point to different destinations - Include analytics and tracking - Require ongoing service subscription - May expire if subscription ends For use cases like sharing a Google Calendar link, course resources, or studio documentation, **static QR codes are the better choice**. ## Recommended Free Services ### QR Code Generator (qr-code-generator.com) - **URL:** https://www.qr-code-generator.com/ - **Type:** Static QR codes (free tier) - **Features:** - No account required - Download as PNG, SVG, or EPS - Customize colors and add logo - No expiration - **Best for:** Simple, permanent QR codes for URLs ### QRCode Monkey (qrcode-monkey.com) - **URL:** https://www.qrcode-monkey.com/ - **Type:** 100% static, always free - **Features:** - High-resolution downloads - Custom colors, gradients, and eye shapes - Logo embedding - No watermarks or registration required - **Best for:** Professional-looking QR codes with branding ### GoQR.me - **URL:** https://goqr.me/ - **Type:** Static QR codes - **Features:** - Minimalist interface - Instant download - Various content types (URL, text, vCard, etc.) - Open-source project - **Best for:** Quick generation without customization needs ## Example Use Case: Google Calendar Embed Link For a link like: ``` https://calendar.google.com/calendar/embed?src=southwesternrecording%40gmail.com&ctz=America%2FLos_Angeles ``` **Process:** 1.
