A converter that does the work in your browser and stays out of the way.
transformpipe turns documents into other documents. Markdown into a finished HTML page, and HTML, Word files and spreadsheets into Markdown. Drop a file, see what it became, take it away as Markdown, HTML, plain text or a PDF.
Everything normalises to Markdown, because Markdown is a format you can read, diff, and keep for twenty years without owning the tool that made it.
The conversion runs in your browser. Signed out, no file is sent anywhere — there is no upload to trust, because there is no upload. Sign in and the Markdown is kept in your account so a document follows you to another machine, and it stays private until you share it.
The exported HTML is one file with its styles inline. It asks the network for nothing, which means it opens the same on a laptop with no connection in five years as it does today.
The same conversions are reachable from a terminal, from a pull request, and from an assistant: there is a public API, a dependency-free command-line client, a GitHub Action that publishes the Markdown a pull request changed, and an MCP server so a model can convert and share documents on your behalf. The documentation covers all of it.
