QR Code Generator With Logo

Add your logo to the centre of a QR code without breaking it. Error correction level H, a capped overlay area and a live scannability warning.

QR code

Enter some text above to build the QR code.

The code is always generated at error-correction level H, the highest of the four. Level H spends about 30% of the symbol on Reed-Solomon repair data, which is precisely why a logo can sit in the middle at all: the modules your logo hides are treated as damage and reconstructed from the rest. The pad is capped two ways — it never covers more than a fifth of the code area, and it is never allowed to reach the three corner finder squares, which a scanner needs intact to find the code in the first place. On a short payload the code is physically smaller, so that second cap tightens automatically. The four-module quiet zone around the edge is always left clear.

Shorter content means fewer modules, bigger modules and a code that scans from further away — link to a short URL rather than pasting a long one. Your logo is read and drawn entirely inside your browser; neither the image nor the text you encode is ever uploaded.

What is the QR Code Generator With Logo?

Putting a logo in the middle of a QR code is easy to do badly. This generator encodes at error-correction level H, the highest of the four, then draws your logo on a rounded white pad in the exact centre.

  • Always encodes at error correction level H (about 30% recovery)
  • Logo pad capped at 20% of the code area and kept clear of the finder squares
  • Live warning when the overlay grows past what is safe
  • Rounded or square white pad, with an adjustable border
  • Shows the module count and QR version for the content you entered
  • Runs entirely offline in your browser

How to use the QR Code Generator With Logo

  1. 1

    Type or paste the link or text you want the code to carry.

  2. 2

    Drop your logo onto the upload area — a PNG with a transparent background works best.

  3. 3

    Set the logo width and white border with the sliders, watching the covered-area percentage.

  4. 4

    Check the green confirmation says the overlay is inside the safe limit.

  5. 5

    Download the PNG, then scan it with a real phone before you print or publish it.

About the QR Code Generator With Logo

Putting a logo in the middle of a QR code is easy to do badly. This generator encodes at error-correction level H, the highest of the four, then draws your logo on a rounded white pad in the exact centre. Level H sets aside roughly 30% of the symbol for repair data, so the modules your logo hides are treated as damage and rebuilt by the scanner.

Two limits keep the result readable. The pad never covers more than a fifth of the code area, and it is never allowed to reach the three corner finder squares that a camera uses to locate the code at all. Short content makes a physically smaller code, so on those the logo is reduced automatically and the tool tells you why.

Everything runs in your browser. Your logo is read and drawn locally, the text you encode never leaves your device, and the PNG is written straight to your downloads folder. Nothing is uploaded to a server, which also means the tool keeps working with no connection.

Frequently asked questions

Does adding a logo to a QR code stop it working?

Not if the logo stays small and central. Error correction level H can rebuild roughly 30% of a damaged symbol, so a centred logo covering under a fifth of the area is recovered. Cover too much, or overlap a corner finder square, and scanning starts to fail.

How big can a logo on a QR code be?

As a rule of thumb, keep the logo and its white border inside 20% of the code's total area, which is roughly 44% of its width. This tool enforces that ceiling for you and tightens it further on small codes where a big pad would clip a finder square.

What is error correction level H and why does it matter here?

QR codes come in four error-correction levels, L, M, Q and H. Level H spends the most of the symbol on Reed-Solomon repair data and can reconstruct about 30% of it. That redundancy is the only reason a logo can sit on top of a code at all.

Why did the tool shrink my logo automatically?

Short content produces a small code, sometimes only 21 modules across. On a code that small, a wide centre pad would touch the corner finder squares that scanners use to locate the code. The tool caps the pad to protect them and shows a note explaining it.

Is my logo uploaded anywhere?

No. The image is read by your browser, drawn onto a canvas locally and never transmitted. The same is true of the text you encode. You can disconnect from the internet and the generator will still work.

Should I use a coloured QR code with a logo?

You can, but keep the modules dark against a white background so there is strong contrast. Black scans most reliably. Inverting the colours, or using a light module colour, causes failures on older phone cameras.
