What it does
Transmute is a free open-source converter and compressor for images, audio, video, documents, structured data, and 3D models. It is deployed on the user's own infrastructure.
A shared conversion service can process several file families through one deployment instead of maintaining a separate web tool for each. The documented catalogue includes CSV/JSON/YAML and model formats alongside media. Conversion and same-format compression are separate operations. Self-hosting also means that the installation and available compute resources become part of the workflow.
The project includes user accounts, role-based access and API keys, with an OpenAPI-documented REST API for automation. Its README describes trusted-network deployment and gives extra requirements for public exposure. Files are processed on the operator's own server; self-hosting does not supply an external retention guarantee. The advertised lack of size limits is qualified by available storage, rather than implying unlimited capacity.
Strengths
- Covers media, structured data, documents, and model files in one deployment.
Best for
- Teams wanting a self-managed multi-format conversion service
