Webflow CMS Image Compression

Compress and reformat image fields on a Webflow CMS item to .webp or .avif.

This skill does not support images embedded inside Rich Text fields at this time. Tell the user that limitation before starting and only process CMS fields whose schema type is Image or MultiImage.

Important Note

ALWAYS use Webflow MCP tools for Webflow operations:

• Use Webflow MCP's data_sites_tool with action list_sites to discover the site ID when needed
• Use Webflow MCP's data_cms_tool with action get_collection_details to fetch collection schemas
• Use Webflow MCP's data_cms_tool with action list_collection_items to fetch the target CMS item
• Use Webflow MCP's data_assets_tool with action create_asset to create presigned asset uploads
• Use Webflow MCP's data_cms_tool with action update_collection_items to update CMS image fields
• Use Webflow MCP's data_cms_tool with action publish_collection_items to publish the updated item
• All Webflow MCP calls must include the required context parameter (15-25 words, third-person perspective)
• Mutating operations require explicit user confirmation. Ask the user to type confirm before uploading assets, updating CMS fields, or publishing.
• Rich Text embedded images are not supported. Do not parse or rewrite Rich Text HTML for image compression.
