md2linkedin

PyPI version Python versions

md2linkedin converts Markdown text to LinkedIn-compatible plain text by replacing bold, italic, and bold-italic markers with Unicode Mathematical Sans-Serif characters. This preserves visual formatting when pasting into platforms like LinkedIn that do not support Markdown natively.

Installation

uv add md2linkedin

Tip: Run the CLI without installing it through uvx: uvx md2linkedin post.md. Every CLI example below works the same way.

Usage

Python API

# @pyodide
from md2linkedin import convert

md = """
# Exciting News

CLI

# Convert a Markdown file (output: post.linkedin.txt)
md2linkedin post.md

# Specify output path
md2linkedin post.md -o linkedin_post.txt

# Pipe from stdin
echo "**Hello**, *world*!" | md2linkedin

# Keep link URLs in the output
md2linkedin post.md --preserve-links

# Disable monospace code rendering
md2linkedin post.md --no-monospace-code

Key Features

  • Bold: **text** or __text__ → Unicode Sans-Serif Bold (𝗯𝗼𝗹𝗱)
  • Italic: *text* or _text_ → Unicode Sans-Serif Italic (𝘪𝘵𝘢𝘭𝘪𝘤)
  • Bold-italic: ***text*** or ___text___ → Unicode Sans-Serif Bold Italic (𝙗𝙤𝙡𝙙-𝙞𝙩𝙖𝙡𝙞𝙘)
  • Headers: #/##/etc. styled with bold Unicode; H1 is also uppercased between ━ borders
  • Code spans and blocks: backticks, fences and indent stripped; content rendered in Unicode Monospace (𝚌𝚘𝚍𝚎) by default, or kept plain with --no-monospace-code
  • Links: stripped to display text by default; --preserve-links retains URLs
  • Images: replaced by alt text
  • Bullet lists: -/*/+ → •; nested items get one marker per level (‣, ◦, ▪)
  • Ordered lists: numbered in sequence from the list's first number (1., 1. → 1., 2.)
  • Tables: header row in bold, cells joined by |
  • Strikethrough and highlight: ~~text~~ and ==text== → text, markers dropped
  • Blockquotes: leading > stripped at every level of nesting
  • HTML spans: unwrapped, inner text preserved
  • HTML entities: decoded (& → &, etc.)
  • Backslash escapes: resolved (\* → *)
  • Windows line endings: normalised automatically
  • Emojis & non-ASCII: pass through unchanged — no accidental corruption

Limitations

Converting Markdown to LinkedIn-friendly text relies on Unicode Mathematical Alphanumeric Symbols to simulate styling. This approach has notable limitations:

  • Code blocks: Monospace Unicode characters do not enforce true fixed-width alignment on proportional fonts (like LinkedIn's default font). As a result, indentation and column alignment in code blocks will often break visually.
  • Tables: Markdown tables are flattened to one line per row, with a bold header and cells joined by |. Nothing keeps the columns aligned on LinkedIn's proportional font, so wide tables are better rewritten as lists.
  • Accessibility: Screen readers often read Unicode mathematical characters aloud individually (e.g., "mathematical sans-serif bold b") instead of as complete words, making the content difficult for visually impaired users to understand.
  • Searchability: Text styled with these Unicode characters may not be indexed properly by LinkedIn's search algorithm, meaning people searching for your keywords might not find your post.
  • Markdown extensions: Only CommonMark plus tables, strikethrough, autolinks and ==highlight== are read. Task-list checkboxes stay as literal [ ]/[x] and footnotes are flattened (text[^1] → text^1); see What Gets Transformed.
