How it works

Three steps to your converted file

Everything happens in your browser tab - upload, pick a format, download. The heavy lifting runs on our servers.

01

Upload your file

Drag and drop, click to browse, or paste a URL. Batches take up to 20 files at once - 230+ input formats across video, audio, image, document, and archive types.

02

Choose an output format

Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

03

Convert & download

Hit Convert and grab your download link moments later. Originals are erased when the job completes; results are cleared within about an hour.

What is an MD file?

An MD file is a plain text document containing Markdown, a lightweight markup language created by John Gruber and Aaron Swartz. The format uses non-alphabetic characters (such as hashes for headers and asterisks for emphasis) to define formatting syntax that is human-readable in its raw form and easily convertible to valid XHTML or HTML. It is the de facto standard for documentation in version control systems like Git.

How to open an MD file

As strictly plain text, MD files can be opened and edited in any basic text editor such as Microsoft Notepad or Apple TextEdit. For a rendered preview of the formatting, specialized editors like Obsidian, Typora, or Visual Studio Code are recommended.
