Why does a logo not break the QR code?

The generator uses the highest error correction level (H), which can recover about 30% of the data. A logo covering under a quarter of the center leaves enough redundancy to scan.

How big can the logo be?

Keep it under about 25% of the code width. Larger logos start to cover too much data for error correction to recover. Always test the finished code before printing.

How does the logo not stop the code from scanning?

The code is generated at error correction level H, the highest, which can reconstruct roughly 30% of the data if it is obscured. A logo placed over the center, covering less than a quarter of the area, leaves enough redundancy for scanners to read the rest.

What logo size is safe?

Stay under about 25% of the code's width. The slider caps the logo within a safe range, but the smaller the logo, the more reliable the scan. Always test the result on a phone before printing in bulk.

Can I change the QR code color too?

Yes. Pick any dark foreground color, keeping strong contrast against the white background — a ratio of at least 3:1 is needed for reliable scanning. Avoid light colors and gradients, which confuse scanners.

Is my logo or URL uploaded anywhere?

No. The QR code and logo are composited on a canvas in your browser. Neither the destination URL nor the logo image is sent to any server.

Logo QR Code Generator — Branded QR with Logo

How to use Logo QR Code Generator

Add your logo to the middle of a QR code without breaking it. This generator encodes your URL or text at the highest error-correction level, then overlays your uploaded logo on a clean white pad so scanners still read the surrounding data. Adjust the logo size and the code color, preview live, and download a print-ready PNG — a branded QR that looks deliberate rather than generic.

Enter the URL or text you want the code to encode.
Upload a logo image to place in the center (optional).
Adjust the logo size slider, keeping it under about 25%.
Pick a dark QR color with strong contrast if you want branding.
Preview the code, then download the PNG.

Your data never leaves your device — 100% private processing.

Why error correction makes logos possible

QR codes build redundancy into every code through Reed–Solomon error correction. At level H, around 30% of the modules can be missing or covered and a scanner can still rebuild the original data. That is the headroom a center logo uses: by covering only the middle — away from the three corner finder patterns scanners rely on to locate the code — and staying under roughly a quarter of the area, the logo sits within the recoverable budget. The white pad behind the logo prevents its edges from merging into nearby modules, which keeps the contrast crisp and the decode reliable.

Correction level	Recoverable	Logo overlay
L	7%	Not recommended
M	15%	Tiny logos only
Q	25%	Small logos
H	30%	Best for logos

Designing a branded code that still scans

A branded QR has to balance looks against readability. Keep the logo centered and modest in size, and prefer a simple, high-contrast mark over a busy full-color image that competes with the pattern. Maintain a dark code on a light background — inverting the colors or using pale foregrounds sharply reduces scan success. Preserve the quiet zone border, and never recolor or cover the three corner squares. Most importantly, test the finished PNG with several phones and apps and from a normal scanning distance before committing it to print; a code that looks great but fails to scan defeats its purpose.
