How to convert text to Markdown
Plain text is the easiest format to turn into Markdown — every Markdown file is plain text, with a few extra characters carrying the formatting. The work is in the structure: marking which lines are headings, which are lists, and what deserves emphasis. Here are the three ways to do it, from fastest to most hands-on.
(Searching for txt to markdown or text to md? Same thing — .md is simply Markdown's file extension, and this page converts plain text to .md files.)
Use this free converter Fastest
- 1Paste your text into the box at the top of this page — or switch to Upload file and drop a
.txtfile (up to 1 MB either way). - 2Click Convert to Markdown — conversion runs in seconds, right here, with no signup.
- 3Copy the Markdown or download it as a
.mdfile.
Under the hood it's the same engine Resolve247 uses to prepare knowledge-base content for AI chatbot training: it normalises whitespace and line endings, keeps your paragraphs and list-like lines intact, and returns a clean .md file ready for LLM ingestion. Your text is processed in memory and never stored.
Add Markdown syntax by hand Most control
Markdown was designed to be written by hand in any text editor. For a short document, adding the syntax yourself gives the cleanest possible result — you decide exactly what's a heading, what's a list, and what gets emphasis.
# Plain text in… # …Markdown out Shipping policy # Shipping policy Orders ship in 2 working Orders ship in 2 working days. Options: days. Options: Standard delivery - Standard delivery Express delivery - **Express delivery**
Mark headings with #, list items with -, bold with **double asterisks**, then save the file with a .md extension. The quick guide below covers the entire syntax in one table.
Python: markitdown Best for batches
Microsoft's markitdown converts whole folders of files to Markdown — overkill for one note, exactly right for hundreds. The same loop handles .txt, .pdf, .docx and .xlsx files alike.
pip install "markitdown[all]"
from markitdown import MarkItDown md = MarkItDown() result = md.convert("notes.txt") print(result.text_content)
For plain text the conversion is light-touch — the value is the uniform pipeline: point it at a mixed folder and every file comes out as Markdown.
Quick guide to Markdown formatting
New to Markdown? It expresses formatting with plain characters instead of tags — which is exactly why LLMs parse it so reliably. Use this table to add formatting to your text by hand, or to read what the converter produces:
| Formatting | Markdown format | Notes |
|---|---|---|
| Heading | # Title ## Section ### Sub | 1–6 # marks set heading levels 1–6 — the document's structure for both readers and LLMs. |
| Bold | **bold text** | Renders as bold text. |
| Italic | *italic text* or _italic text_ | Renders as italic text. |
| Bold + italic | ***both*** | Renders as both. |
| Underline | — | There's no underline syntax in Markdown — use bold or italic for emphasis instead. |
| Strikethrough | ~~crossed out~~ | Renders as |
| Bullet list | - item or * item | One item per line; indent two spaces to nest. |
| Numbered list | 1. first item | Numbers auto-correct when rendered — 1. on every line also works. |
| Link | [link text](https://example.com) | Text in square brackets, URL in parentheses. |
| Image |  | A link with a leading !. (This converter outputs text only.) |
| Inline code | `code` | Backticks render text in monospace. |
| Code block | ``` … ``` | Triple backticks on their own lines fence off a multi-line block. |
| Quote | > quoted text | A > at the start of a line renders a blockquote. |
| Table | | Col | Col | | Pipes separate cells; a | --- | --- | row under the header row defines the table. |
Why convert text to Markdown for AI?
Plain text looks LLM-ready already — and it's true that a .txt file is far cleaner input than a PDF or a web page. What it lacks is structure. To a language model, a wall of plain text gives no signal about where one topic ends and the next begins, which lines are titles, or which items belong together. Markdown adds exactly that signal, at a cost of almost zero extra tokens.
Structure is what makes RAG pipelines work well. Retrieval systems split documents into chunks before embedding them, and the best splitting points are real section boundaries — which in Markdown are explicit # headings rather than guesses. Chunk on real boundaries and each chunk stays coherent, which directly improves retrieval and answer quality.
It's also why Markdown is the standard input for AI chatbot training. When Resolve247 trains a support chatbot on your help docs or knowledge base, content is normalised to Markdown first — clean, structured source material is half of what makes an anti-hallucination guarantee possible. An AI can only answer from your content reliably if your content was ingested cleanly.
And the cost of converting is nothing: Markdown is plain text. It opens in every editor your .txt does, diffs in git, and converts onwards to anything. You lose nothing and gain the structure machines need.

Text to Markdown FAQ
Yes. Paste text or upload a .txt file and download the Markdown with no signup, no card and no email. There's a fair-use rate limit to keep it fast for everyone — a Resolve247 free trial removes it.
Nothing is stored. Whether you paste text or upload a file, it's converted in memory and the Markdown is returned in the same request — we keep neither your text nor the output once the response is sent.
Plain text is already most of the way to Markdown — Markdown is plain text, with a few characters carrying the formatting. The converter normalises whitespace and line endings, keeps your paragraphs and list-like lines intact, and returns a clean UTF-8 .md file ready for LLM ingestion. To add formatting the text never had — headings, bold, links — use the Markdown quick guide on this page.
1 MB per conversion, whether pasted or uploaded — roughly 150,000 words, so almost any document fits. Need more? A Resolve247 free trial lets you train your AI on multiple files at once, each up to 30 MB.
Yes — that's what it's built for. This is the same conversion engine Resolve247 uses to ingest knowledge-base content for its AI support chatbots, so the output is structured for chunking, embedding and chatbot training.
Whichever is easier — both run through the same engine and produce identical Markdown. Pasting is quickest for notes and snippets already in your clipboard; uploading suits saved .txt files. Both are capped at 1 MB.
TXT to MD is the same thing as text to Markdown — .md is simply the file extension Markdown uses. To convert TXT to Markdown, paste your text (or upload a .txt file) in the converter above, click Convert to Markdown, and download the result as a .md file. You could rename a .txt to .md by hand, but converting also cleans up the text — and gives you somewhere to start adding real structure.
No. The converter writes the Markdown for you, and the output stays perfectly readable as plain text. If you want to add formatting yourself afterwards — headings, bold, links — the quick guide above covers the entire syntax in one table.
This page is tuned for plain text, but the suite covers those formats: use the Word to Markdown converter for .docx files and the PDF to Markdown converter for PDFs — same engine, same free, no-signup deal.
