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
- Middle of the code. The centre's the safest place to cover — the bits a scanner needs to lock on sit at the corners and edges.
- Keep it small. Rough guide: don't let the logo cover much more than the spare capacity you've got. At H (~30%), a logo taking up a slice of the centre is comfortable. Bigger than that and you're rolling the dice.
- Hands off the corners. The three big squares, and the little alignment squares, are how a scanner finds its bearings. Never cover them.
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:
- Dark code, light background. Keep a strong gap between the squares and what's behind them.
- Don't invert it. Loads of scanners expect dark-on-light; a pale code on a dark ground fails silently.
- Mind the quiet zone. Keep the margin round the code clear of artwork, or scanners can't find its edges.
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.
