Can I Add My Logo to a QR Code?
Direct Answer
Yes, as long as the logo is small (roughly 20–25% of the code's area, centered) and the code uses a high error correction level, since the logo effectively covers part of the encoded data.
Key Facts
- ✓Keep the logo under ~25% of the total code area
- ✓Use error correction level H for logo overlays
- ✓Always test-scan the final version before printing at scale
- ✓A centered logo is safer than one near a corner — corner squares must stay clear
Full Explanation
A QR code absorbs moderate visual "damage" thanks to error correction, and a centered logo is treated the same as a smudge by the decoding algorithm. Keep it small, centered, and never overlapping the three corner squares (used for orientation) — covering those breaks the scan entirely. UnlimitedQRCodes.com generates clean QR codes without a built-in logo tool; for a logo overlay, generate the code here, add the logo with an image editor following the placement rules above, and test-scan before printing.

What is error correction in a QR code?
Built-in redundancy that lets a QR code scan correctly even if part of it is damaged or covered — level H recovers from up to ~30% damage, which is why it's used for logo overlays.
What size should a QR code be for printing?
It depends on the application — 3cm × 3cm minimum for table tents, 5–8cm for window stickers, 8–15cm for outdoor signage. Adding a logo increases the recommended minimum size.
