Frequently Asked Questions

Is my data sent to any server?
No. All QR code generation happens entirely in your browser using JavaScript. Your data never leaves your device.
What is the maximum content length?
The maximum depends on the error correction level: L supports ~4296 characters, M ~3391, Q ~2420, and H ~1852 alphanumeric characters. The tool shows a character counter to help you stay within limits.
Does adding a logo affect scanning?
Adding a logo covers part of the QR code data. The tool automatically sets error correction to H (highest) when a logo is added, which allows up to 30% of the code to be obscured while remaining scannable. Keep logos small for best results.
Should I download PNG or SVG?
Use PNG for digital sharing (social media, messaging, websites). Use SVG for print materials (business cards, posters, flyers) as SVG scales to any size without losing quality.
