Let your AI agent convert CR3 to PS
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 CR3 files in my Downloads folder to PS”
Or run it yourself:
filestarcli -i file.cr3 -c "convert to ps"

A CR3 file is an image created by select Canon digital cameras, such as the EOS M50 and EOS R. It may store uncompressed RAW image data exactly how it was captured by the CCD or compressed RAW (C-RAW) image data depending on the camera setting selected. CR3 files were introduced in 2018 with the release of the Canon EOS M50, replacing .CR2 files.
A PS file is an image saved in the PostScript page description language. It may contain vector graphics, raster graphics, and text. PS files can be printed directly by a PostScript printer (i.e., containing a Raster Image Processor) without being opened in an application.
