Chart rendering
Bar, line, pie, doughnut, area, scatter, radar and bubble charts are rebuilt as interactive Chart.js canvases.
Phase 2 · Production Ready
Python 3.7+
Open source
PowerPoint in.
Faithful HTML out.
Convert PowerPoint presentations into portable HTML bundles with 98%+ visual fidelity.
No runtime web dependencies: Chart.js from CDN is the only external fetch in generated output.
01 · Features
Everything on the slide survives the trip
Text, charts, shapes, media and effects are rebuilt as native HTML, CSS and SVG, not baked into screenshots.
Custom shapes to SVG
Arrows, flowchart blocks and freeform custom paths convert to crisp, infinitely scalable SVG.
SmartArt text extraction
SmartArt graphics fall back to clean, structured text that keeps the original hierarchy intact.
Animation preservation
Entrance effects are re-expressed as native CSS keyframes, replayed on every slide change.
Shadows & reflections
Shape shadows carry over as CSS box-shadows; reflections render in WebKit browsers.
150 DPI images
Embedded pictures export at up to 150 DPI, sharp on retina screens and projectors alike.
Video & audio embedding
Media stays media: clips and audio keep playing directly in the browser, not as posters.
Tables & hyperlinks
Fully styled tables and live hyperlinks, including merged cells and themed fills.
Embedded fonts
Fonts embedded in the deck are de-obfuscated and re-served as WOFF webfonts, so typefaces survive the trip.

02 · Quick Start
Two commands and a browser
Clone the repo, install dependencies, and point the converter at a deck. Output is a portable HTML bundle — HTML, CSS, JS and assets that open straight from disk.
terminal: install
pip install -r requirements.txt
terminal: convert
python scripts/convert_pptx_to_html_v2.py presentation.pptx output/python scripts/convert_pptx_to_html_v2.py presentation.pptx output/ 300 # custom DPIOpen output/presentation.html in any browser. No server, no build step. Pass a trailing DPI argument like 300 to control image resolution.
03 · Phase comparison
What Phase 2 adds
Phase 1 produced solid static decks. Phase 2 closes the gap on the hard parts: charts, vector shapes, motion and effects.
