Add your logo without breaking the scan
Create your QR above, select Customize, then upload a square logo under Center mark. You can also change the colours, the pattern, and the corner style, and add a frame message.
Every change is checked. The design is rendered, decoded again as if by a phone camera, and compared against your payment details. If it no longer reads, the download is blocked and you are told what to change. A QR that looks good and fails at the counter never leaves this page.
Why a logo is risky at all
A logo works by covering part of the pattern. QR codes carry error correction that can rebuild missing data, which is why this is possible, but the budget is finite and it is being spent on your logo rather than on smudges, creases, and bad light.
When a logo is added, the generator switches to the highest error correction level and, if needed, redraws the code at a larger size. That is why a QR with a logo has a denser pattern than one without.
Choosing a logo that survives
- Square, or close to it. Wide logos have to shrink to fit and become unreadable anyway.
- Simple and high contrast. At the size it ends up, a detailed logo is a smudge. A single letter or a simple mark reads better than a full wordmark.
- Solid background, or a transparent PNG. The generator places a clean backing behind the logo so it does not blur into the pattern.
- PNG, JPG, WebP, or SVG, up to 2 MB.
Your logo file is read in your browser and used to draw the image there. It is never uploaded.
Colours are the other trap
Scanners need a dark pattern on a light background. Two mid tones that look fine on a bright screen fail on a printed sticker under a shop light. The generator refuses combinations that do not have enough contrast and suggests a fix.
Keep the background white or very light, and the pattern genuinely dark. If you want brand colour, put it in the frame and the surrounding layout rather than in the pattern itself.
Test the printed copy, not just the screen
The scan check confirms the image decodes. It cannot predict your printer, your paper, or the lighting at your counter. Print one, scan it with two different phones, and send ₹1 before ordering a batch. Matte lamination rather than gloss, because glare in the middle of a QR is exactly where a centre logo already made things harder.
