Let your AI agent convert PGM to WMZ
Claude Code, Codex, Cursor and other agents can do this on your computer with Filestar. Your files stay on your machine.
Install Filestar and add it to your agents:
npm install -g filestar
filestarcli agent install
Then ask your agent:
“Convert the PGM files in my Downloads folder to WMZ”
Or run it yourself:
filestarcli -i photo.pgm -c "convert to wmz"
Runs on your computer, so your files stay on it. Works on Windows, macOS and Linux. 50 free conversions with the npm install, no account needed.
Can my AI agent convert PGM to WMZ?
Yes. Install the Filestar CLI with npm install -g filestar and your agent can run filestarcli -i photo.pgm -c "convert to wmz" on your computer, so your files stay on it.
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.
A WMZ file is a Windows Metafile (.WMF) compressed with GZIP. Microsoft Office and Visio save vector graphics this way to reduce their size. Windows Media Player skins also use the .wmz extension, but those are ZIP archives and are a different format.
