Endpoints

Method	Path	Description
POST	/convert-embed/	Upload images → download base64 text file
POST	/extract-images/	Upload text file → download ZIP of images

Supports JPEG, PNG, and HEIC formats. Max 10 files per request (configurable).

No distortion. Embed → extract is lossless. Raw image bytes are base64-encoded and decoded back exactly — no re-encoding at any stage.

pip install -e ".[dev]"
pixelfuse serve --reload
