How the logo stays scannable
QR codes are built with error correction, meaning a portion of the pattern can be covered or damaged and the code still reads correctly. This tool generates every code at the highest correction level (H, roughly 30% tolerance) and sizes your logo to stay safely inside that margin. It's the same technique used by every professional QR generator — the difference here is nothing gets added afterward. No corner badge, no small print, no company name stamped on your download.
For best results, use a simple, high-contrast logo — a wordmark or icon reads more reliably at small sizes than a busy, detailed image.
Frequently asked questions
Will adding a logo break my QR code?
Not if it's sized correctly, which this tool handles automatically by keeping the logo within the safe error-correction margin. Always test-scan your code before printing or publishing it.
Is there really no watermark on the download?
Correct — the only image in the final file is your QR code and your logo. Nothing from this site is added to the exported PNG.
What image formats can I upload for my logo?
PNG, JPG, and SVG are all supported, up to 2MB. PNG with a transparent background usually looks cleanest at the center of the code.
Do I need an account to download my QR code?
No. There's no sign-up anywhere on this tool — generate and download in one step.
