FIRST CH TOOLS / 14 MARP SLIDES

Marp Markdown → Slides

Write Markdown, get Marp slides as you type — text on the left, slides on the right. Save them as PDF through the print dialog, or download a self-contained HTML deck you can open anywhere. Includes a Japanese-friendly theme. Everything runs in your browser; your draft is never sent to a server.

How to Use

  1. Write MarkdownPaste into the editor or open a .md file. A line containing only --- starts the next slide.
  2. Pick a themeChoose the Japanese-friendly firstch theme or Marp's built-in default / gaia / uncover. A theme: directive in your Markdown wins over this selector.
  3. Save as PDFClick "Save as PDF" and pick "Save as PDF" as the print destination — one slide per page.

About This Tool

Rendering uses Marp's official marp-core (MIT License), bundled for the browser. It is the same engine as Marp CLI and the VS Code extension, so a deck written here works unchanged with the marp command. PDF export goes through your browser's own print pipeline: the slide dimensions become the @page size, so you get one slide per page with no margins.

The firstch theme tunes line height, letter spacing and heading rules for Japanese text. Set it explicitly at the top of your Markdown: 

---
marp: true
theme: firstch
paginate: true
---

Images, math and syntax highlighting all work (math via KaTeX, code via highlight.js). Your draft is never uploaded — the only network requests come from images you reference by external URL in your own Markdown. Several of our other tools are also callable directly by AI agents through our MCP server (using these tools from AI agents).
