How to Change Thumbnail Image on Wix Website

Want to update the image that appears when your Wix website is shared on social media or messaging apps? This guide explains how to change the thumbnail image on your Wix website using the built-in SEO tools and settings.

What Is the Thumbnail Image on Wix?

In Wix, the thumbnail image is part of the Open Graph metadata. It determines how your website preview appears when shared on platforms like Facebook, Twitter, or WhatsApp. This image is a critical part of your website's branding and first impressions.

You can set a custom thumbnail through the Wix Editor or Wix SEO settings for each page or the entire website.

Steps to Change Thumbnail Image in Wix

Follow these steps to update your Wix website’s thumbnail image using the Wix Editor and SEO tools:

1. Open your Wix website in the Wix Editor.
2. Click on Menus & Pages from the left panel.
3. Select the page you want to change the thumbnail for.
4. Click the three dots (...) next to the page and select SEO Basics.
5. In the SEO panel, scroll to the Social Share section.
6. Click Upload Image or Replace to set a new thumbnail image.
7. Click Done, then Publish your website to apply changes.

Set Homepage Thumbnail on Wix

If you want to update the main website thumbnail (usually the homepage), repeat the steps above for your homepage. This image is what appears when someone shares your main website URL.

What About Favicon and Thumbnail?

The favicon is the small icon shown in browser tabs. While it’s not the same as the thumbnail image, both can be changed from the same area in your Wix settings.

To change the favicon:

• Go to your Wix Dashboard
• Click Settings > Website Settings
• Scroll to Favicon and click Upload
• Publish your changes

Wix Thumbnail Not Updating?

Sometimes, even after changing the thumbnail image, platforms like Facebook or LinkedIn may still show the old one. This happens due to caching on their end.

Try the following:

• Double-check that the new thumbnail is saved and the site is published
• Use Facebook’s Sharing Debugger to refresh the link preview
• Clear your browser cache and recheck
