Question 1

What is a Dynamic QR Code?

Accepted Answer

A dynamic QR code encodes a permanent short link to our domain (e.g. qr.omniide.com/abc123) rather than your final destination URL. This allows you to change the destination URL anytime after printing without needing to re-print your physical packaging, stickers, or marketing collateral.

Question 2

Is OmniQR free to use?

Accepted Answer

Yes! OmniQR offers completely free static QR code generation with custom presets, logo uploads, and vector exports with no login required. Dynamic QR codes with editable destinations and real-time scan analytics are also available for free with an account.

Question 3

Why does OmniQR return HTTP 302 Found instead of 301?

Accepted Answer

OmniQR strictly returns HTTP 302 Found redirects with Cache-Control: no-store. Unlike HTTP 301 (which browsers and smartphones permanently cache), HTTP 302 guarantees that whenever you update your destination URL in the dashboard, any phone scanning the printed code will immediately be routed to your new destination target without delay.

Question 4

Can I put my company logo in the center of the QR code?

Accepted Answer

Yes! OmniQR allows you to upload any brand logo (PNG, JPG, or SVG). When a logo is uploaded, OmniQR automatically locks the error correction level to Level H (30% redundancy) and mathematically caps the logo size at 22% of total area to guarantee reliable scannability on all cameras.

Question 5

What export formats are supported?

Accepted Answer

OmniQR provides print-ready vector SVG exports for large format printing (billboards, banners, posters) and ultra-crisp 1024px PNG exports for digital and merchandise use.
