Legacy Chat will be retired on February 14, 2026. To avoid service interruptions to your
end users, switch to enhanced Chat (formerly Messaging for In-App and Web). Enhanced Chat
offers many of the legacy Chat features that you love plus asynchronous
conversations that can be picked back up at any time. Learn about migrating in Help and Trailhead.
To
customize your chat window and chat buttons, create one or more Salesforce Sites. Then,
upload the images that you want to use as static resources. Static resources enable you to
upload content that you can reference in a Visualforce page. Each static resource has its
own URL that Salesforce uses to access the images when the chat window loads.
Create a Salesforce Site to host your images.
When you create a Salesforce Site for your Chat deployment, provide the following information.
A site label and site name
A site contact
The active site’s home page
A site template
Upload your branding images as static resources.
Note The maximum size for a standard chat window image is 50 pixels.
