Let your AI agent convert PPSX to PGM
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 PPSX files in my Downloads folder to PGM”
Or run it yourself:
filestarcli -i file.ppsx -c "convert to pgm"

A PPSX file is a slide show created by Microsoft PowerPoint or another presentation program, such as OpenOffice Impress or SoftOffice Presentations. It contains a finished collection of slides that are used for slide show playback.
A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
