How to customize a QR code (without breaking it)
Colors, logos, sizes — what QR Code with Logo lets you change, and what you should leave alone. Browser-based, free, no signup, runs entirely on your device.
Generating a QR code sounds like it should require an app — and historically it did. QR Code with Logo runs the same thing in your browser tab, with one tap and no signup.
Open the tool: QR Code with Logo — Browser-only. Nothing is sent to a server.
What you can customize in QR Code with Logo
QR Code with Logo exposes the options that matter without overwhelming you with the ones that don't:
- Size — pick the smallest size that still scans reliably for your use case
- Color — foreground and background. Keep contrast high; aesthetics shouldn't fight readability
- Margin / "quiet zone" — the empty border around the QR code. Don't skip this; scanners need it
- Logo overlay — embed a brand image in the middle. Works because of built-in redundancy in the encoding
What you shouldn't change
- The error-correction level (raise it, don't lower it)
- The encoding format (let QR Code with Logo pick the best one for your input)
- The aspect ratio (always square — non-square QR codes are unreadable)
