About

About Transmute


Transmute is a free, open-source, self-hosted file converter built for privacy and automation.

It lets you convert images, video, audio, documents, spreadsheets/data, subtitles, fonts, diagrams, and more entirely on your own hardware. No third-party uploads. No watermarks. No artificial file size limits.

Transmute is designed for home labs, self-hosters, makers, and anyone who wants the convenience of online file converters without sending private files to someone else's servers.

It includes:

  • A clean web UI
  • Docker-based deployment
  • Built-in authentication
  • Per-user data isolation
  • API keys
  • OIDC / SSO support
  • A REST API for automation and integrations
  • Multiple built-in themes

Transmute is MIT licensed and will remain free and open source.

Why support Transmute?


Transmute does not have a big infrastructure bill. It is self-hosted by design, and I want to keep it that way.

Sponsorship mainly supports the time and care that goes into maintaining the project:

  • Fixing bugs
  • Testing new formats and conversion paths
  • Improving the Docker image and release process
  • Writing docs and examples
  • Reviewing issues and pull requests
  • Keeping the website and project resources available
  • Continuing to build features without turning Transmute into a paid SaaS product

You do not need to sponsor Transmute to use it. But if it saves you time, replaces a paid converter, or becomes part of your home lab, a small monthly contribution goes a long way.
