If you are implementing SharePoint in your organization and creating sites, then you should know how to change the SharePoint site logo and thumbnail.
In this tutorial, I will show you how to change the SharePoint site logo and thumbnail.
Whenever you create a new SharePoint Online site, you will see that the default logo with the site name abbreviation will be added to your SharePoint site.

If you want to change the default logo added to your SharePoint site, you can change the look and feel of your SharePoint site.
SharePoint Site Logo Size
The recommended size for the SharePoint Online site logo is 64px x 64px.
The default SharePoint On-Premises logo size appears in the following size:
- Width: 180 pixels
- Height: 65 pixels

Change SharePoint Site Default Logo
Now, let me show you how to change the logo of a SharePoint Online site, which can be a team site or a communication site.
Here are the steps to do this:
- Open your SharePoint Online site to which you want to change the site logo.
- On the top right side of the SharePoint Home page, click on the Gear or Settings icon.
- Select the Change the look option.

- In the next window, click on the Header section.

- Then, scroll down to the bottom of that pane; you can see two types of logos, like Site logo thumbnail and Site logo.

- After that, to change the Site logo thumbnail and site logo, click on the image icon under them. Click on the Save button after uploading the images.

- From now on, you can see that the changes have been applied. Look at the site logo that will appear before the site name.

- You can see the Site logo thumbnail within the Microsoft 365 ecosystem where the SharePoint site appears.
- For example, on the SharePoint start page, you can see the SharePoint site cards with a logo thumbnail.

This is how you can change the site logo and site logo thumbnail in SharePoint Online.
Here are a couple of essential things you should know about the SharePoint site logo and site logo thumbnail:
- If you do not upload a site logo, it will be displayed with the site name abbreviation in its place. The thumbnail logo will also be visible with the site name abbreviation.


- If you change the SharePoint site logo without the Site logo thumbnail, the logo will only appear on the SharePoint site. The abbreviation logo will appear on all locations where the SharePoint site logo thumbnail appears.

Output:

- If you upload a Site logo thumbnail without a site logo, a thumbnail will be added to the site logo automatically. The same image will be visible in the place of the site logo, as well as where the thumbnail should appear.

Output:


- When you click on the site logo, it will always direct you to the SharePoint site’s home page. Unfortunately, it is not possible to change the SharePoint site logo URL.
