RST Converter
FileFlip converts RST files into 61 other formats entirely inside your browser, using Pandoc, MuPDF and ImageMagick compiled to WebAssembly. The RST file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert an RST file?#
- Drop your RST file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert RST files online?#
Yes, because nothing is uploaded. FileFlip converts RST files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.

What is an RST file?#
An RST file holds reStructuredText, the markup David Goodger designed in 2001 for Python documentation, where directives and interpreted text roles extend the syntax with cross-references, footnotes and generated content that Markdown has no built-in equivalent for.
Write in reStructuredText for Python documentation or any Sphinx-built site that needs directives, cross-references and generated indexes.
Convert reStructuredText to Markdown when the destination lives outside the Sphinx or Python ecosystem, since most directives don't have a Markdown equivalent.
The RST file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
RST questions people ask#
What is reStructuredText used for?
reStructuredText is the markup behind Python's own documentation and most Sphinx-built documentation sites, chosen because PEP 287 made it the standard format for Python docstrings. Its directive system lets a project define custom content types, which is why documentation with heavy cross-referencing tends to land on it over Markdown.
What's the difference between RST and Markdown?
reStructuredText defines directives and interpreted text roles as a formal extension mechanism, where Markdown relies on each implementation inventing its own extensions. RST is also more strictly specified, so a Docutils-conformant file parses the same way everywhere, at the cost of a more verbose syntax than Markdown's.
Can I convert RST to Markdown without losing anything?
Headings, paragraphs, lists and basic emphasis convert from reStructuredText to Markdown cleanly. Directives, most notably Sphinx-specific ones like toctree or code-block with language-aware highlighting, plus footnotes and substitution definitions, have no direct Markdown equivalent and either get dropped or flattened to plain text.
