Uploading your Logo
The store’s theme will determine the location and the size of the logo in the header . You can save your logo as either a GIF, PNG, or JPG (JPEG) file type, and upload them from the Admin of your store.
The logo image is uploaded in the specific location on the server. Any image file with the name “logo.gif” is used as the default theme logo.
Full path: app/design/frontend/[vendor]/[theme]/web/images/logo.gif
Relative path: images/logo.gif
If you don’t know the size of the logo, or any other image that is used in your theme, open the page in a browser, right-click the image, and inspect the element.
Besides the logo in the header, your logo is also displayed on email templates and on PDF invoices and other sales documents. The logos used for email templates and invoices have different size requirements, and must be uploaded individually.
