About FileConvertMage
FileConvertMage exists for one job: change format A into format B. The first launch tools convert still JPEG, PNG, and WebP files in the browser. They tell you what cannot survive — transparency, animation, metadata — before you download.
It is not a same-format image workbench, a structured-data reshaper, a document editor, or a wrapper around a conversion API. Ads and analytics scripts are not loaded.
