HTML to PowerPoint Converter

First time? If setup_complete: false above, run ./SETUP.md first, then set setup_complete: true.

Convert HTML to PowerPoint (.pptx) with excellent Hebrew/RTL support using PptxGenJS.

Setup (One-time)

cd ~/.claude/skills/html-to-pptx && npm install

Quick Usage

Basic conversion:

node ~/.claude/skills/html-to-pptx/scripts/html-to-pptx.js input.html output.pptx

Hebrew document with RTL:

node ~/.claude/skills/html-to-pptx/scripts/html-to-pptx.js hebrew.html presentation.pptx --rtl

Convert URL to PowerPoint:

node ~/.claude/skills/html-to-pptx/scripts/html-to-pptx.js https://example.com slides.pptx

Complex HTML as images (pixel-perfect):

node ~/.claude/skills/html-to-pptx/scripts/html-to-pptx.js complex.html slides.pptx --mode=image

Conversion Modes

Mode	Description	Best For
`text`	Parse HTML, create native PPTX elements	Simple HTML, editable text
`image`	Screenshot HTML, embed as images	Complex layouts, exact rendering
`auto`	Auto-detect best mode	Default

Options

Option	Description	Default
`--mode=<mode>`	text, image, auto	auto
`--rtl`	Force RTL for Hebrew/Arabic	auto-detect
`--title=<title>`	Presentation title	auto
`--author=<author>`	Author name	AVIZ
`--layout=<layout>`	LAYOUT_16x9, LAYOUT_4x3	LAYOUT_16x9
`--font=<font>`	Default font	Heebo (Hebrew) / Arial
`--font-size=<size>`	Font size in points	18
`--background=<color>`	Background color (hex)	-

Examples

Hebrew presentation:

node ~/.claude/skills/html-to-pptx/scripts/html-to-pptx.js hebrew.html slides.pptx --rtl --font=Heebo

Split by sections:

node ~/.claude/skills/html-to-pptx/scripts/html-to-pptx.js doc.html slides.pptx --slide-per=section

Custom styling:

node ~/.claude/skills/html-to-pptx/scripts/html-to-pptx.js doc.html slides.pptx --font=David --font-size=24 --background=F5F5F5

Pipe HTML:

echo "<h1>שלום עולם</h1>" | node ~/.claude/skills/html-to-pptx/scripts/html-to-pptx.js - output.pptx --rtl

Hebrew Best Practices

Use <html lang="he" dir="rtl"> in HTML
Always add --rtl flag
Use Hebrew-supporting fonts: Heebo, David, Noto Sans Hebrew
For complex layouts, use --mode=image for pixel-perfect results

Slide Structure

The converter auto-detects slide boundaries:

<section> elements
<article> elements
.slide class
<hr> elements

Or use --slide-per=".my-slide" for custom selectors.
