Logo Overlay

Upload a PNG or JPG logo to overlay on the center of your QR code. Error correction is automatically set to High (H) for best scan reliability.

Pro Tips

  • Keep it short. Shorter URLs and text produce simpler, faster-scanning QR codes. Use a URL shortener for long links.
  • High contrast matters. Dark foreground on light background scans most reliably. Avoid light-on-light or dark-on-dark.
  • Test before printing. Always scan your QR code with multiple devices before printing on business cards, flyers, or signage.
  • Error correction H for logos. When adding a logo, High error correction ensures the code remains scannable even with 30% of data obscured.
  • WiFi QR codes are a hit. Print one for your office, Airbnb, or restaurant. Guests scan to connect instantly without asking for the password.

What Is a QR Code?

A QR (Quick Response) code is a two-dimensional barcode that stores data in a grid of black and white squares. Originally invented in 1994 by Denso Wave for tracking automotive parts, QR codes have become ubiquitous in marketing, payments, restaurant menus, event tickets, and contactless sharing. Any smartphone camera can read them instantly without installing a separate app.

Unlike traditional barcodes that store data in one dimension, QR codes encode information both horizontally and vertically, allowing them to hold up to 4,296 alphanumeric characters. They also include built-in error correction, meaning a QR code can still be read even if part of it is damaged or obscured — which is why logo overlays work without breaking functionality.
