将 html-ppt 生成的 HTML 演示文稿一键转换为 PPTX / Convert html-ppt HTML presentations to PPTX in one click
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.

将 html-ppt 生成的 HTML 演示文稿一键转换为 PPTX 文件。
工作原理
- headless Chrome 截图:利用 Chrome 的
#/N深度链接,逐页将 HTML 渲染为 PNG 图片 - 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 |
--quality | JPEG 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
- Headless Chrome screenshots: Renders each slide to PNG via Chrome's
#/Ndeep links - 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]
| Parameter | Description | Default |
|---|---|---|
<html-file> | Path to the HTML file | Required |
N | Number of slides to convert | all (auto-detect) |
--ratio | Slide aspect ratio | 16:9 |
--quality | JPEG quality (1-100), or png for lossless | 92 |
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.
