QR Code with Logo
Generate a QR code with your logo centered on top. Error correction is locked to High and the logo size is capped automatically, so the code stays scannable.

About this QR code with logo generator
A logo sitting on top of a QR code is, technically speaking, deliberate damage — it blocks whatever data modules were underneath it. This only works because QR codes carry Reed-Solomon error-correction redundancy specifically designed to let a scanner reconstruct data that's missing or obscured, up to a limit that depends on the correction level chosen when the code was built. That's why, whenever a logo is present, this tool locks error correction to High (roughly 30% redundancy) automatically rather than leaving it as a normal option — anything lower risks a code that looks fine but won't actually scan.
The logo's rendered size is also capped in code, not just left to chance: it's limited to roughly a fifth of the code's overall width, comfortably within what High correction can reliably recover from, with a white backdrop drawn behind it so the logo's edges (especially if your image has an irregular shape or transparency) don't leave stray, partially-obscured modules confusing a scanner right at the boundary.
None of this is a mathematical guarantee for every possible situation, though — extremely long content already consumes more of a code's structure before a logo is even added, leaving proportionally less spare redundancy no matter the correction level. Test any logo QR code with an actual phone camera before printing it somewhere it needs to work reliably, especially for longer URLs or text.
As with color choices on a plain QR code, contrast matters here too: keep the foreground and background reasonably distinct from each other, since low contrast can undermine scanning regardless of how well the logo itself is handled.
Nothing you enter or upload is sent anywhere; the QR code and logo compositing both happen locally in your browser using a small JavaScript library for the underlying QR encoding.
Frequently asked questions
Why can't I choose a lower error correction level when I add a logo?
A logo covers part of the code's data, and only High error correction (~30% redundancy) reliably leaves enough spare capacity for a scanner to reconstruct what's underneath. Lower levels risk a code that looks correct but fails to scan.
How big can my logo be?
The tool automatically caps the rendered logo to roughly a fifth of the code's width, regardless of your original image's size or shape, since anything larger risks exceeding what error correction can recover from.
Is a logo QR code guaranteed to always scan?
Not in every situation. Very long content already uses more of a code's structure before a logo is added, leaving less spare redundancy. Test the result with an actual phone camera before relying on it somewhere important, especially for longer URLs or text.
Why is there a white box behind my logo?
It gives the logo clean, consistent edges against the code, so an irregular logo shape or a logo with transparency doesn't leave partially-obscured modules right at its boundary, which can confuse a scanner more than a clean cut does.
Is my content or logo uploaded anywhere?
No. The QR code is generated and the logo composited entirely in your browser; nothing is sent to a server.
