Cardixn · Free Tools
The premium free QR code generator
Unlimited QR codes. High-res exports. No watermark. No sign-up required.
Most QR code generators lock resolution, add watermarks, or force you to pay for SVG. Cardixn's QR generator is free, unlimited, and gives you 4K PNG plus vector SVG on every export — perfect for print, packaging, or business cards.
Dynamic QR codes (upgrade)
For businesses, upgrade to dynamic QR codes — you can change the destination URL without re-printing the QR. Perfect for menus, event schedules, or campaigns that evolve.
Track every scan
Dynamic QRs include analytics: total scans, unique visitors, geographic breakdown, and device types. Know exactly how your print campaigns perform.

Frequently asked questions
Is Cardixn free to use?
Yes. You can create, share and receive digital business cards on the free plan. Premium templates, analytics and NFC provisioning are available on paid tiers.
Do recipients need the Cardixn app?
No. Cards open in any modern browser via a public link or QR code. Recipients can save the vCard to their phone with one tap.
Can I edit my card after sharing?
Yes. Updates apply instantly. Anyone who scanned or saved your card always sees the latest information — no need to re-share.
Is my data secure?
Cardixn uses end-to-end encrypted storage, row-level security, and never sells your data. You control what is public and what stays private.
Does Cardixn work offline?
Cards are cached for offline viewing once opened, and QR codes can be downloaded as high-resolution PNGs to print on badges, packaging or business collateral.
