16.1 Adding a Center Logo

The Logo tab lets you place a center image over the QR Code. The builder advertises PNG or SVG up to 2 MB with a 1:1 aspect ratio recommended.

The logo is embedded into the styling payload used when rendering and downloading the QR.

16.2 Uploading the Logo

1. Open the Logo tab.
2. Select or drag the logo file into the Center Logo area.
3. Use Browse files if needed.
4. Wait for the preview to update.
5. Adjust Logo size.
6. Scan-test the preview or saved QR before distribution.

16.3 Logo Size

The builder provides a Logo size control. The stored image-size ratio is derived from the selected percentage. Larger logos cover more QR modules and therefore require more careful testing.

16.4 Removing a Logo

Use Remove logo when you want the QR to return to a design without a center image. During editing, you can also upload/replace a saved logo.

16.5 Logo and Error Correction

Because a logo obscures part of the QR pattern, use an appropriate error-correction level. The builder explains that higher correction tolerates more visual damage or logo coverage but creates a denser code.

16.6 Recommended Logo Preparation

1. Use a simple mark rather than fine text.
2. Prefer a square or near-square logo.
3. Use a transparent background when appropriate.
4. Avoid very large logos that cover finder patterns or too much data.
5. Check the QR at the smallest intended print size.
6. Test on both light and dark device camera interfaces.

16.7 When Not to Use a Logo

For high-risk environments—small labels, low-quality printing, curved surfaces, glare, outdoor wear, or distant scanning—a plain high-contrast QR may perform better than a heavily branded design.
