How to Add a Logo to a QR Code Without Ignoring Readability

Start with the final payload and a simple logo

Use the exact destination you want to distribute. An original fictional example is a workshop page at https://example.com/workshop with a simple lettermark. This illustrates the task; substitute your actual verified destination before distribution.

The logo input accepts PNG, JPEG and WebP up to 2 MB, with decoded dimensions limited to 4096 pixels per side and the tool's pixel limit. SVG logo files are not accepted. The image is read and re-encoded locally; it is not uploaded to a BarcoBatch image service. A clean mark with limited tiny detail is easier to recognize at the small center size than a full wordmark.

Choose the available controls for readability

Use a dark QR foreground and a very light background. The tool applies its conservative contrast guard, including a minimum 7:1 ratio; this is an application rule, not a certification that a camera will read every print.

You can choose Square modules or Soft corners. The engine preserves its functional patterns and the clear border, and chooses the permitted center-logo placement itself. The form does not offer arbitrary logo-size, corner-pattern or quiet-zone overrides. Do not enlarge the center image or add text over the exported symbol in another editor.

Understand why a dense logo QR may be refused

The style engine uses error-correction level H. A percentage describing recoverable codewords is not a matching percentage of visible area that a logo may safely cover. Function patterns, data layout and the final print still matter; see the error-correction guide for the technical distinction.

If the tool reports that the QR is too dense for a safe central logo, shorten the content when that can be done without changing its meaning, remove the logo, or use the general QR generator. Do not silently change the target address or bypass the guard. Longer content and logo placement can interact with function modules; the tool deliberately refuses combinations it cannot safely place.

Check the exported file before using it in artwork

The exported SVG contains the re-encoded logo image, so it does not need an external logo URL. Preserve its proportions and clear border. For print sizing and avoiding blurred edges, use the QR print-quality guide.

1. Generate after the content, logo, colors and style are final.
2. Download the exact PNG or SVG you will distribute.
3. Decode it locally with the QR Scanner and compare the actual content with your intended value.
4. If it is a URL, check its destination separately. The logo tool also supports text and does not verify URL ownership or fetch a webpage.
5. Try the downloaded image on the reader devices your audience uses.
6. Print a sample at final size and test the actual material and lighting before a larger run.
