What is Meta Converter?

For ComfyUI JPEG output, workflows are saved as separate JSON files. For NovelAI JPEG output, a companion metadata file is created. The application also provides quality and resize controls, Eagle library conversion and a command-line interface.

All processing runs locally on the CPU and no GPU is required.
