Html2pptx

Convert local HTML/WebDeck slide presentations into editable PowerPoint PPTX files. Use when the user provides an .html/.htm deck and wants editable text, shapes, SVG, and ECharts content instead of a screenshot-only export.

File contents

html2pptx

This is the Claude Code / opencode project-skill entry point for this repository.

The implementation lives in the shared skill folder:

skills/html2pptx/SKILL.md
skills/html2pptx/scripts/html2pptx.py
skills/html2pptx/scripts/html_dom_to_editable_svg.js
skills/html2pptx/scripts/svg_to_pptx/

Run the converter from the repository root:

python skills/html2pptx/scripts/html2pptx.py input.html -o output.pptx

If Chrome or Chromium is not auto-detected:

python skills/html2pptx/scripts/html2pptx.py input.html -o output.pptx \
  --chrome "/path/to/Google Chrome or Chromium"

--chrome-path is also accepted as an alias. On Windows:

python skills/html2pptx/scripts/html2pptx.py examples/basic-deck.html -o basic-deck.pptx \
  --chrome-path "C:/Program Files/Google/Chrome/Application/chrome.exe"

For debugging bad pages:

python skills/html2pptx/scripts/html2pptx.py input.html -o output.pptx \
  --workdir /tmp/html2pptx-debug --keep-workdir

Inspect svg_output/NN_slide.svg.

Good fit:

Fixed 16:9 HTML/WebDeck slides.
Plain single-page HTML that should be auto-wrapped into one 1280x720 slide.
DOM text, CSS boxes, lines, SVG diagrams, and ECharts charts that should remain editable.
Decks where PowerPoint editability matters more than screenshot-perfect rendering.

Current converter strengths:

ECharts instances are forced or rebuilt with SVG renderer where possible.
Uniform rounded CSS borders are preserved as editable stroked rounded rectangles.
Inline SVG children inside text nodes are extracted instead of being swallowed by text conversion.
Common Font Awesome Free solid <i class="fa-..."> icons are inlined as SVG paths before extraction.

Known limits:

Long webpages are clipped to the slide viewport.
Full HTML documents nested inside a slide may need preprocessing.
CSS pseudo-elements, filters, shadows, complex masks, and external icon fonts may degrade.
