Free online TXT to MD converter

Source format: txt

TXT is a plain text format that stores unformatted text only. It is one of the simplest and most widely supported file types, used for notes, logs, scripts, and documentation without styling. A .txt file usually contains only characters and line breaks, so it opens in almost any text editor on any operating system.

Target format: md

MD is a Markdown document format. Markdown adds lightweight formatting syntax to plain text, making it easy to create headings, lists, links, emphasis, code blocks, and other structured content while keeping the file readable in a normal editor. .md files are commonly used for documentation, README files, notes, and content that may later be rendered on websites, in version control platforms, or in documentation tools.

How to convert txt to md

Converting TXT to MD is usually straightforward because both formats are text-based. In many cases, the conversion is simply a matter of renaming the file extension from .txt to .md if the content is already meant to be Markdown or if you want to store plain text in a Markdown file.

1. Open the .txt file in a text editor such as Notepad, TextEdit, VS Code, Sublime Text, or similar.
2. Review the content and decide whether it should remain plain text or be enhanced with Markdown syntax.
3. If the file already contains Markdown-compatible text, save it as filename.md using File → Save As.
4. If needed, add Markdown formatting such as headings with #, lists with - or 1., emphasis with *text* or **text**, and links with [label](url).
5. Verify the result by reopening the .md file in a Markdown editor or preview pane.

Important: if the source text has no Markdown syntax, changing only the extension will not create formatted content. The file will still be plain text, just stored with an .md name.

If you want a free browser-based option, you can convert the file on 101convert.com without installing any software.

For batch work or automation, command-line tools can help. For example, if you only need to rename files, use mv notes.txt notes.md on macOS or Linux, or ren notes.txt notes.md in Windows Command Prompt. If the content needs actual Markdown transformation, a script or editor macro is usually required because plain TXT does not contain formatting information to convert automatically.

Notes on quality and compatibility

The main limitation of TXT to MD conversion is that plain text does not preserve formatting. If the source .txt file has no Markdown syntax, changing the extension alone will not create headings, tables, or other rich structure. In that case, the result is still just plain text stored in a Markdown file.

Compatibility is generally excellent because Markdown is widely supported, but different renderers may interpret some syntax slightly differently. Also, if the original text contains special characters, indentation, or line breaks that matter, check the output carefully to make sure the Markdown layout still looks correct. For documentation workflows, it is often best to manually add Markdown structure after conversion rather than relying on automatic formatting.
