Math-based · fully scannable

Your logo is the code.

QRlfy generates QR codes where the data modules themselves form your logo. Not an overlay. Not a hack. The math makes the logo scannable.

Regular QR codes are ugly black squares. Most “branded” generators just paste your logo on top and hope error correction covers the damage.

Brands avoid QR codes because they clash with their identity. QRlfy fixes that.

Three steps. Real math underneath.

01

Upload your logo

We extract its colors and build a target map — the exact pixel pattern your code should resemble.

F
02

We solve the math

Gaussian elimination over the QR's free bits, padding included. The modules bend to your logo. No overlay.

Get a scannable QR

Every code clears 5/5 decode rungs and stays spec-valid. Export and ship it anywhere.

It’s Artcode, done properly.

QRlfy uses Artcode — a technique that treats QR error correction as a system of linear equations over GF(2). Every QR code has free padding bytes. We solve for the padding values that make each data module land on the right shade of your logo.

The result isn’t an approximation. It’s a fully spec-compliant QR code that a standards body would approve. We verify every output against a 5-rung decode harness — native resolution, downscaled to 512px, 256px, and two Gaussian blur levels that simulate camera defocus.
