How to convert plain text to Markdown
- Paste text into the box or choose a
.txtfile. - Select Convert to Markdown.
- Check the Markdown source and rendered preview.
- Copy the result or download the
.mdfile.
Plain text is valid Markdown, but structure still matters
A plain text file can already open as Markdown. The problem is that its structure is often only visible to a person. A line may look like a heading because it is uppercase. A list may use bullet characters that Markdown does not understand. A web address may not become a link.
This converter turns those clear patterns into Markdown syntax. It uses an H1 for the first detected title, H2 headings for later sections, hyphens for bullet lists, standard markers for numbered lists, and angle brackets for bare links and email addresses.
Fixed rules keep the result predictable
The conversion is deterministic. The same input gives the same output every time. It does not use AI to rewrite sentences or make creative formatting choices. Existing Markdown stays in place, and ordinary sentences keep their words and order.
Plain text cannot store bold, italic, linked labels, or table cells. Paste the original formatted copy into the rich text to Markdown converter when that formatting is still available. Use the Markdown table generator for copied rows and columns.
Convert TXT files without an upload
You can open a .txt or .text file up to 1 MB. Pasted input can contain up to 100,000 characters. The browser reads and converts it locally, so notes and internal project text do not leave the page.
The finished Markdown works in Git, Obsidian, documentation systems, and context files for AI agents. The token counter shows how much context the result will use.
Frequently asked questions
Paste plain text or choose a .txt file, then select Convert to Markdown. The tool detects clear headings, common bullet characters, numbered lists, and bare links. Check the source or rendered preview before you copy or download the result.
It detects underlined headings, short isolated title-case or uppercase headings, bullets that use common symbols, numbered items that use a closing bracket, web addresses, and email addresses. Existing Markdown syntax stays in the document.
No. The conversion uses fixed rules, so the same text always gives the same Markdown. It does not send your writing to an AI service or guess which words should be bold.
Yes. Choose a .txt or .text file up to 1 MB. The converter reads it in your browser and downloads the result as a .md file.
Existing headings, lists, links, code spans, and other common Markdown stay intact. The tool normalises line endings and adds structure only where a plain-text pattern is clear.
Use the Markdown table generator for rows and columns. It handles tab-separated text, CSV, spreadsheet cells, HTML tables, and existing Markdown tables.
Plain text has no stored bold, italic, heading, or link formatting, so this tool detects structure from the words and line layout. The rich text converter reads formatting that is still present when you paste from Word, Google Docs, or a webpage.
Yes. File reading, conversion, preview, copy, and download run in your browser. Your text is not uploaded, you do not need an account, and there is no daily limit.
