The Site Assets Library in SharePoint is a built-in library that stores images, files, and other supporting assets referenced by pages and web parts within a SharePoint site.

Common Use Cases

• Images for pages and news: stores images used in pages, news posts, and Hero web parts
• Branding assets: logos, icons, banners, and design elements reused across pages
• Embedded content: assets used in embeds, callouts, or custom layouts

Benefits

• Automatically created: every modern SharePoint site includes a Site Assets library by default
• Centralized asset storage: keeps images and supporting files in a predictable location
• Permission inheritance: assets follow site-level permissions by default
• Clean page management: separates content (pages) from supporting media (assets)
• Easy reuse: assets can be reused across multiple pages without duplication

Key Considerations

• Not for document collaboration: Site Assets is not intended for working documents
• Permissions matter: users must have access to view assets referenced on pages
• Used automatically by web parts: many web parts save files here without user awareness
• Can grow quickly: image-heavy sites may accumulate large numbers of assets
• Deletion impact: removing assets may break images or web parts on pages where they are used
