How to Add a Logo to a Shopify Store
By default, the logo area of your Shopify store will be replaced by the name of your store, written in text. To upload a logo onto your Shopify store, head over to your admin.
Once you’re in the Shopify admin, click on Online Store. Towards the right-hand side of the screen, click on the green Customize button. Next, click on the Header section.
After you open the Header section in the left-hand side panel, find Logo Image and click on Select Image. Browse through your files to find the image you want to upload.
After uploading, click on the image and then hit Select.
You can then change the size of the logo by dragging the Custom Logo Width toolbar to adjust the size. Once you find the size you want, click Save.
Then, head on back to your eStore to confirm that the logo image file is in place by hitting refresh on your browser.
