Markdown Use Cases This Page Was Built For

Convert

The Chat Answer That Has to Become a Deliverable

ChatGPT or Claude replied in raw Markdown — ## headings, **bold**, a pipe table — and the client expects a document. Paste the whole reply into Convert and take out .doc, PDF or HTML with the heading levels, lists and table borders intact instead of retyping it in Word.

View

A .md File Landed in Your Downloads Folder

README.md, CHANGELOG.md, an exported Obsidian or Notion note — double-clicking opens a wall of hash marks and pipe characters. Drop the file here and read it rendered: task lists tick, fenced code keeps its indentation, tables line up. Syntax you don’t recognise is in the cheat sheet below.

Edit

Writing in Markdown Because Word Fights You

Headings, links and lists are three keystrokes instead of three toolbar clicks. Type on the left, watch the rendered page on the right, and the draft is kept in this browser so a reload doesn’t cost you the paragraph — then export once the wording is settled.

Reverse

Rich Text You Need as Clean Markdown

Copy a doc page, a wiki entry or an email and you normally paste in <span style> soup. Convert runs the HTML back through a Markdown converter, so what lands in your notes app, repo or static site is plain #, - and []() — no leftover font tags.

The viewer supports GitHub Flavored Markdown, including headings, tables, task lists, strikethrough, links and fenced code blocks. Raw HTML is sanitized before display.
