How to brand a QR code (without breaking the scan)

20 June 2026

A plain black-and-white code does the job, but it's anonymous. Nothing about it says who it belongs to. Add your logo and your colours and it earns more trust — and more scans. Here's the snag: every bit of branding nibbles at the code's safety margin. Push too far and you've got a gorgeous code nobody can scan. This is how you stay on the right side of that line.

Why a logo doesn't wreck the code

QR codes carry spare capacity called error correction. At the top levels — Q and H — a code can lose a quarter or a third of itself and still read, because the data's stored with enough repetition to fill the gaps.

That spare capacity is what lets you drop a logo in the middle. The logo hides some modules; the scanner rebuilds them from the redundant data around it. Everything below is just about staying inside that budget.

The safe zone: centred and modest

Turn error correction up first

The logo spends part of your backup budget, so top it back up. Pick Q or H, not L or M, whenever you add one. That single change does most of the work. There's a cost — more correction means more modules, so the code gets a touch denser. Claw it back by keeping the payload short. A tidy link leaves you loads more room than a long one. What makes a good QR code digs into this balance.

Colour and contrast

Colour's fine. As long as the contrast holds up:

Doing it across a whole batch

Branding one code is nothing. The payoff comes when every code in a campaign carries the same logo and colours. In bulkqr you set the branding once — switch on the image embed for your logo, choose your colours and error correction — and it lands on the whole batch. Paste your list and every code comes out on-brand and matching, ready as a ZIP or printable labels.

Test before the print run

Always scan a branded code on a real phone — a cheap one, in normal light — before you print a thousand. If it hesitates, shrink the logo or bump the error correction and go again. A logo that costs you scans isn't worth having. One that keeps the code snappy is the whole point.

And a code needn't point at a web page at all — the same branding works on a WiFi, contact, or campaign code.
