Paste Markdown on the left, check Preview (it shows the same HTML Copy will use), click Copy, then paste into Teams. Preview and paste stay aligned so you are not fixing spacing by hand afterward.

Copy writes rich HTML for Teams' compose box and a plain-text fallback stripped of Markdown syntax. Teams reads the HTML when you paste with Cmd/Ctrl+V.

Teams supports a Markdown-style syntax while you type in the compose box, but pasted Markdown usually stays plain. This converter turns Markdown into rich HTML you can paste with formatting intact.

Use Copy on this page, then paste with Cmd/Ctrl+V into the rich-text composer. Formatting can drop in some browsers or if you select preview text by hand instead of using Copy. Try the Teams desktop app if web paste misbehaves.

Each heading level (# through ######) becomes a semantic H1–H6 tag with inline font sizes tuned for Teams paste (22px for H1, 18px for H2, 15px for H3, and smaller for deeper levels). Preview and Copy use the same inline-styled HTML.

Yes. GFM pipe tables convert to HTML tables that Teams accepts on rich paste. Raw pipe characters pasted without conversion usually stay as plain text.

Yes. Preview and Copy run in your browser. This page does not upload or store your text on a server. Keep your own local backup of important drafts.

Bold, italic, strikethrough, links, lists, blockquotes, inline code, fenced code, tables, and headings H1–H6 with inline Teams-style sizing are supported. Mermaid diagrams and heavy HTML layouts are out of scope.

Teams applies Markdown shortcuts as you type inside the compose box. This tool is for drafts written as normal Markdown elsewhere: preview here, Copy, then paste into Teams without retyping the message.

Yes. Free to use, no signup. Open the page, paste Markdown, preview, and Copy when you are ready.
