Read articleHow to change a Shopify logo and check its quality
Replace your Shopify logo through theme settings, then check the file, proportions, contrast and related surfaces before considering the change complete.
To change a Shopify store's logo, open the theme editor and find the logo settings. Depending on the theme, these may be in Theme settings or the header. After selecting a file, check size, contrast and mobile behaviour.
No width is perfect for every logo. The symbol's proportions, header space and navigation controls determine how large it can become without harming the experience.
Prepare a suitable file
- Use a clean original with enough quality for its displayed size.
- Remove unnecessary transparent margins around the artwork.
- Use transparency where the header background requires it.
- Keep light and dark versions if the design changes backgrounds.
PNG can be useful for transparency; a well-prepared SVG stays sharp if the theme and picker support it. Enlarging a small image file does not restore lost detail.
Shopify brand asset management explains how a logo connects to supported surfaces. Saving the asset does not guarantee that every part of the store uses it automatically.
Change the logo in the theme
- Go to Online Store → Themes.
- Open the editor for the theme you want to review; use a copy when testing a wider change.
- Find Theme settings → Logo or the equivalent header setting.
- Select or upload the file.
- Adjust its width and review the preview before saving.
The theme-settings documentation describes the general process. A custom theme may use different names or separate mobile and desktop logos.
If the logo looks too small
First check empty space in the file. If the canvas is large and the artwork occupies only a small area, increasing the width also enlarges the margins. Cropping the file may solve the problem without making the header taller.
Then review the configured width, available height and alignment. Avoid adding global CSS before identifying which setting limits the result.
If it looks blurred or cropped
| Problem | What to check |
|---|---|
| Blurred | Original quality, resolution used and enlargement applied. |
| Cropped | File proportions and theme container. |
| Unexpected background | Actual file transparency and header colour. |
| Low contrast | The logo version against the visible background. |
Test the header while scrolling too, especially if it is sticky or changes colour. A logo that works over the hero may disappear against a light header.
Mobile: check the whole header
Review the logo alongside menu, search and cart controls. Do not shrink controls or remove interaction space to enlarge the brand. If a mobile logo version exists, use one that remains recognisable.
Test with the actual name or icon, rather than only an empty screenshot. For other store images, see the size and aspect-ratio guide.
Favicon and other surfaces
The favicon is the browser-tab icon. Use a simple version that remains recognisable at small sizes. The favicon guide explains settings and limitations.
Review checkout, accounts, notifications and external channels separately. Changing the theme logo does not prove those surfaces changed. Each may have its own configuration.
A final check
Open home, collection, product and contact pages on mobile and desktop. Check navigation, contrast and the brand link. If the favicon does not update, check a new tab and caching before repeatedly uploading versions without finding the cause.
The main-menu guide complements this header review. If the problem is broader than the logo file, a Shopify design and experience audit can prioritise changes.
