Let your AI agent convert JFIF to TCR
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 JFIF files in my Downloads folder to TCR”
Or run it yourself:
filestarcli -i photo.jfif -c "convert to tcr"

The JFIF (JPEG File Interchange Format) format makes it possible to transfer compressed JPEG files across computers. This graphical file format uses a marker to show various parameters not seen in the standard JPEG file — for instance, pixel size, pixel geometry, among others.
The TCR file format is associated with eBook files specifically used by Psion Series 3 devices. Psion Series 3, a range of personal digital assistants (PDAs) developed in the early 1990s, utilized these files to store and display electronic books (eBooks). TCR files are designed to be compact to suit the limited storage capacities of early PDAs. They contain the text of the eBook, and possibly basic formatting, optimized for the low-resolution screens of the Psion device.
