Set up

Skills are installed by placing their folder where your agent loads skills.

The download comes from github.com/nlj626/html-to-pptx itself, not from our server, so what you get is exactly what its author published.

Install instructions come from the README

Skills do not use an MCP config. Follow the steps in the README below.

html-to-pptx

将 html-ppt 生成的 HTML 演示文稿一键转换为 PPTX 文件。

工作原理

  1. headless Chrome 截图:利用 Chrome 的 #/N 深度链接,逐页将 HTML 渲染为 PNG 图片
  2. pptxgenjs 组装:将 PNG 图片按顺序嵌入 PPTX,每张图片铺满整页

因为是截图方式,PPTX 会 100% 还原 HTML 的视觉效果,包括字体、颜色、布局、渐变等。

注意:输出的 PPTX 中每页是一张图片,不可编辑文字。适合需要分享给只接受 PPTX 格式的场景。

安装

前置依赖

  • Google Chrome(macOS 默认路径 /Applications/Google Chrome.app)
  • Node.js >= 18
  • pptxgenjs:npm install -g pptxgenjs

作为 Claude Code Skill 安装

# 方法 1:通过 skills CLI(推荐)
npx skills add nlj626/html-to-pptx

# 方法 2:手动
mkdir -p ~/.claude/skills
git clone https://github.com/nlj626/html-to-pptx ~/.claude/skills/html-to-pptx

安装后,在 Claude Code 中说"导出 PPTX"即可自动触发。

使用方式

命令行

bash scripts/html-to-pptx.sh <html-file> [N|all] [--ratio 16:9|4:3|3:4|1:1] [--quality N|png]
参数说明默认值
<html-file>html-ppt 生成的 HTML 文件路径必填
N指定转换的页数all(自动检测)
--ratio幻灯片宽高比16:9
--qualityJPEG 压缩质量(1-100),或 png 强制无损92

示例

# 自动检测页数,默认 16:9
bash scripts/html-to-pptx.sh my-deck/index.html

# 指定 8 页
bash scripts/html-to-pptx.sh my-deck/index.html 8

# 4:3 宽高比
bash scripts/html-to-pptx.sh my-deck/index.html all --ratio 4:3

# 更小的文件(JPEG 质量 80)
bash scripts/html-to-pptx.sh my-deck/index.html all -- --quality 80

# 无损 PNG 格式
bash scripts/html-to-pptx.sh my-deck/index.html all -- --quality png

作为 Claude Code Skill 使用

安装后,在对话中说:

  • "导出 PPTX"
  • "把这个 HTML 转成 PPT"

与 html-ppt 的关系

本项目是 html-ppt 的配套工具,将 HTML 演示文稿转换为通用 PPTX 格式,方便分享给不支持 HTML 的场景。

html-ppt 使用 MIT 协议,本项目同样使用 MIT 协议,完全兼容。

html-to-pptx

A companion tool for html-ppt that converts HTML presentations to PPTX in one click.

How It Works

  1. Headless Chrome screenshots: Renders each slide to PNG via Chrome's #/N deep links
  2. pptxgenjs assembly: Embeds PNG images into PPTX, each filling the entire slide

Since it uses screenshots, the PPTX perfectly preserves the HTML visual output, including fonts, colors, layout, and gradients.

Note: Each slide in the output PPTX is an image — text is not editable. Ideal for sharing with audiences that only accept PPTX format.

Installation

Prerequisites

  • Google Chrome (macOS default path: /Applications/Google Chrome.app)
  • Node.js >= 18
  • pptxgenjs: npm install -g pptxgenjs

Install as Claude Code Skill

# Method 1: via skills CLI (recommended)
npx skills add nlj626/html-to-pptx

# Method 2: manual
mkdir -p ~/.claude/skills
git clone https://github.com/nlj626/html-to-pptx ~/.claude/skills/html-to-pptx

After installation, just say "export to PPTX" in Claude Code to trigger.

Usage

Command Line

bash scripts/html-to-pptx.sh <html-file> [N|all] [--ratio 16:9|4:3|3:4|1:1] [--quality N|png]
ParameterDescriptionDefault
<html-file>Path to the HTML fileRequired
NNumber of slides to convertall (auto-detect)
--ratioSlide aspect ratio16:9
--qualityJPEG quality (1-100), or png for lossless92

Examples

# Auto-detect slides, default 16:9
bash scripts/html-to-pptx.sh my-deck/index.html

# Specify 8 slides
bash scripts/html-to-pptx.sh my-deck/index.html 8

# 4:3 aspect ratio
bash scripts/html-to-pptx.sh my-deck/index.html all --ratio 4:3

# Smaller file (JPEG quality 80)
bash scripts/html-to-pptx.sh my-deck/index.html all -- --quality 80

# Lossless PNG
bash scripts/html-to-pptx.sh my-deck/index.html all -- --quality png

Use as Claude Code Skill

After installation, say any of these in your conversation:

  • "export to PPTX"
  • "convert HTML to PPT"

Relationship with html-ppt

This is a companion tool for html-ppt. It converts HTML presentations to the widely-supported PPTX format for sharing in scenarios where HTML is not accepted.

Both projects use the MIT License and are fully compatible.
