Are QR codes created on MyLogoQR really 100% free?
Yes, absolutely. MyLogoQR is completely free for both personal and commercial use. There are no paid tiers, hidden subscriptions, scan limits, watermark requirements, or credit card sign-ups. You can generate unlimited codes anytime.
Do generated QR codes ever expire?
No, they will never expire. All QR codes created on MyLogoQR are static barcodes. The target destination (URL, Wi-Fi password, vCard contact, or text) is encoded directly into the pixel pattern. As long as your destination link is active, your QR code will scan forever.
Is my data (like Wi-Fi passwords or vCard contacts) uploaded to your server?
Never. MyLogoQR was specifically engineered with a 100% client-side zero-knowledge architecture. All matrix calculations, style configurations, and image exports happen strictly within your local browser memory using JavaScript. No confidential passwords, phone numbers, or image logos are ever sent across the internet to our servers.
Can I use these QR codes on commercial products and packaging?
Yes. You retain full, unrestricted commercial rights to all generated files. You can freely print them on restaurant tables, product packaging labels, corporate business cards, storefront signage, and promotional billboards with zero royalties or fees.
How does adding a custom logo not break the barcode scan?
Whenever you upload a brand logo, MyLogoQR automatically switches to Level H (High) Reed-Solomon Error Correction. This cryptographic algorithm builds redundant mathematical parity blocks into the barcode matrix, allowing up to 30% of the center to be overlaid with your custom image without hindering modern smartphone camera decoders.
Which export format should I choose: PNG or SVG?
Choose SVG (Scalable Vector Graphics) for all professional printing, graphic design (Illustrator, Photoshop, Figma), and commercial merchandise. Vectors can be enlarged to billboard size with razor-sharp edges. Choose PNG for digital presentations, websites, email footers, and direct social messaging.
Can I change the destination URL after printing?
Because our QR codes are static and permanently hardcoded into the graphic pattern, the URL cannot be modified after download. If you need future flexibility, simply point the QR code to your own domain redirect (e.g. yourdomain.com/go/menu) which you can forward anywhere later.
