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.
