What is it?
ConvertX is a self-hosted online file converter written in TypeScript on Bun and Elysia. You upload files through a web interface, pick a target format, and the app runs the conversion on your own server, so files do not need to pass through a third-party service.
The project wraps a range of established conversion tools behind one interface. Images go through Vips, ImageMagick and GraphicsMagick, video and audio through FFmpeg, documents through LibreOffice, Pandoc and Calibre, and 3D assets through Assimp. The converter table in the project lists the supported input and output counts for each tool.
It is deployed with Docker, using a single container and a mounted data volume. Accounts, password protection, file cleanup on a schedule, and optional conversion concurrency limits are configured through environment variables.
