For Stickers.
Most QR generators give you a black-and-white square. Print that on a sticker and it looks like a barcode someone forgot to remove. QRKong gives you a code that holds its own next to your logo, in your colours, ready for any sticker printer.

How to make a sticker-ready QR code
- Paste the destination URL into QRKong (the page you want scanners to land on).
- Pick a dot pattern, colour, and eye style. Drop your logo in the centre — error correction handles up to ~30% blockage.
- Download the PNG at 1024 px or above. Upload it to your sticker printer — most accept high-res PNG just fine.
- Upload to Sticker Mule, VistaPrint, UPrinting, or your own cutter. Test the first sticker off the press before you order 500 more.
Common questions
Download the PNG at high resolution — QRKong exports at 512px, which is sharp enough for stickers up to about 10 cm at standard print DPI.
For very large-format stickers (window decals, floor graphics), print at the largest output size and keep the design high-contrast.
Yes, as long as you keep strong contrast — dark code on a light background scans best, and anything below a 4:1 contrast ratio risks misreads.
Pure black on white is bulletproof. If you want brand colour, recolour the dots rather than the background, and keep the background close to white.
For arm's-length scanning (laptop, water bottle, fridge), a sticker as small as 2 cm × 2 cm works if the design is clean and the printer is sharp.
For a metre or more of scanning distance (window, shop wall), use the 10:1 rule: code size = distance ÷ 10. A 50 cm scan needs a 5 cm code.
Yes — QR codes have built-in error correction that lets you blot out up to ~30% of the code with a logo without breaking the scan.
Keep the logo to under a quarter of the code's area, and centre it. Always test the printed sticker with two or three phones before doing a full run.
For a small run with weatherproof vinyl: Sticker Mule, MakeStickers, or UPrinting. For business volumes: VistaPrint, PrintRunner, or PrintPlace.
Upload the PNG from QRKong, pick a die-cut shape, and order. Most ship in under a week.
