Transmute
Transmute is a free, open-source, self-hosted file converter. Convert images, video, audio, data, and documents on your own hardware with no file size limits, no watermarks, and full privacy.
The tool provides a self‑hosted service that transforms a wide range of file types—including images, video, audio, data sets, and documents—directly on the user’s own hardware. It runs as open‑source software, allowing anyone to install it locally and perform conversions without relying on external services. Because processing occurs on the user’s machine, there are no imposed file‑size limits, no automatically added watermarks, and the data remains private.
It is aimed at individuals or organizations that need to handle media and document conversion while maintaining full control over their files and infrastructure. The software is suitable for developers, hobbyists, or small teams that prefer an on‑premises solution rather than cloud‑based alternatives.
The project is currently in an experimental stage, offering basic conversion capabilities and a quick‑start guide for deployment. Its open‑source license permits modification and redistribution, enabling users to adapt the converter to specific workflows or integrate it with other self‑hosted services.
