Customize your social images with the Social Image Generator

The Social Image Generator (SIG) helps you automatically create a unique image for each post before sharing it to your connected social accounts. This guide will show you how to enable the feature, customize your image, and use default settings to streamline your workflow.

This feature is only available with a paid Jetpack Social plan.

Enable the Social Image Generator feature

To turn on the Social Image Generator:

1. Log in to WP Admin → Jetpack → Social.
2. Toggle on Automatically share your posts to social networks.
3. Switch on Enable Social Image Generator.

When enabled, SIG will be active by default for new posts. If it’s turned off, you can still activate it manually in the post editor.

The Social Image Generator works only with the Block Editor. It is not compatible with the Classic Editor or plugins that rely on it, such as WooCommerce.

Customize your social image in the post editor

Once enabled, you can preview and customize your image directly in the editor:

1. In the Block Editor, click the Jetpack icon (or Social icon) in the top-right corner to open the Social panel.
2. Scroll to the Social Image Generator section and click Settings.
3. Customize the following options:
   • Preview: See a live preview of your social image.
   • Image Type:
     • Featured Image – Uses your post’s featured image.
     • Custom Image – Upload your own image.
     • Plugin Default Image – Uses the default image set by your site admin.
     • No Image – Displays only your post title or custom header.
   • Custom Header: Add your own text to appear on the image. By default, this uses the post title.
   • Templates: Choose from a selection of predesigned layouts.
4. Click Save when you’re done.

Set a default image for new posts

Site admins can configure a default image for social shares. This image is used when no featured or custom image is selected in the post.

To set a default image:

1. In WP Admin → Jetpack → Social, click Change defaults under Enable Social Image Generator.
2. Under Default Image, click to upload or select an image from the Media Library.
3. Click Save.
