File Converters
Any office format, any direction
Convert documents, spreadsheets, presentations, markup and images between formats — locally, with no upload and no queue.
Conversion is the tax on working with other people: you write in one format and somebody needs another. The awkward part is that most converters are servers, so the price of the conversion is a copy of the document.
These run in the browser. Word, Markdown, HTML and spreadsheets are all parsed into one intermediate document model, and the PDF, Word and HTML writers all consume that model — which is why the same structure survives whichever direction you convert in.

Worth knowing
Every conversion loses something, and it is better to know what. Converting to Markdown discards formatting with no Markdown equivalent rather than approximating it. Converting to a lossy image format discards detail permanently, so always convert from the best original rather than from a copy that has already been through the process. Keep the source file; treat the conversion as an export.
