Let your AI agent convert AVIF to FB2
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 AVIF files in my Downloads folder to FB2”
Or run it yourself:
filestarcli -i photo.avif -c "convert to fb2"

It is an image compression codec file with the same quality as .jpeg, but that is ten smaller. It supports HDR (High Dynamic Range). SDR (Standard Dynamic Range), and WCG (Wide Color Gamut) images.

The FB2 (FictionBook 2.0 File) format is an open XML-based ebook format specifically designed for fictional literature, although it can also accommodate non-fiction. Unlike other ebook formats, FB2 focuses on the structure and content of the book, rather than its appearance. This means that the layout, font, and styling are determined by the e-reader device or software, offering a more uniform reading experience across different platforms.
