Let your AI agent convert SFD to JBG
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 SFD files in my Downloads folder to JBG”
Or run it yourself:
filestarcli -i file.sfd -c "convert to jbg"
Runs in Filestar's cloud and needs a Filestar plan.
Can my AI agent convert SFD to JBG?
Yes, with a paid Filestar plan: this skill runs in Filestar's cloud. Install the Filestar CLI with npm install -g filestar and your agent can run filestarcli -i file.sfd -c "convert to jbg".
SFD (Spline Font Database) is the native, text-based source format of the FontForge font editor. It stores a font's glyph outlines, metrics, kerning, OpenType tables and editing state, so a font can be reopened and edited losslessly and then exported to TrueType, OpenType, WOFF or Type 1.
Created by JBIG (Joint Bi-level Image Experts Group), JBG is a lossless file format that contains both colored and monochrome images. Commonly used to compress fax images, and it has better compression than G3 and G4 compression codecs.
