Can You Insert a Logo into a QR Code?
Yes, but with strict rules. The logo should not occupy more than 30% of the code area and must be centered. QR error correction allows reading even with partial damage.
Optimal Logo Sizes
The logo should be compact — about 10-15% of the total code area. Square format is preferable to round. Minimum size depends on error correction level (ECC level).
Contrast and Colors
The main code color should be as dark as possible on as light a background (black on white — ideal). You can use brand colors, but contrast must remain high (minimum 7:1).
Testing Readability
Always test the code with several scanners. Check on different devices and applications. If the code reads poorly — increase contrast or reduce the logo.
Creation Tools
Use specialized branded QR code generators that automatically follow error correction rules and support preview with test scanning.
