Let your AI agent convert SK to WEBP
Claude Code, Codex, Cursor and other agents can do this with Filestar. This skill runs in Filestar's cloud and needs a paid Filestar plan.
Install Filestar and add it to your agents:
npm install -g filestar
filestarcli agent install
Then ask your agent:
“Convert the SK files in my Downloads folder to WEBP”
Or run it yourself:
filestarcli -i photo.sk -c "convert to webp"

This format is a vector images file in the Sketch Drawing program, which serves to edit and create interface designs, applications and software shells. SK-files contain objects and layers which can be edited independently of each other.
A WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
