Getting started

Install the high-level package, pass it PPTX bytes, and receive SVG or PNG output together with diagnostics and support coverage.

Requirements

Node.js 22 or later for Node.js applications and package tooling.
A modern browser bundler for browser applications.
Font files or known font directories when presentation text must match closely.

No office installation required. pptx-glimpse runs in-process. Rendering does not start PowerPoint or LibreOffice and does not require a conversion service.

Install

Terminal


npm install pptx-glimpse

The high-level package includes compatible document and editor packages as runtime dependencies. Install a lower-level package directly only when your application imports it.

Render your first slide

In Node.js, read the file as bytes and pass it directly to the converter.

render-slide.ts


import { readFile, writeFile } from "node:fs/promises";
import { convertPptxToPng } from "pptx-glimpse";
 
const pptx = await readFile("presentation.pptx");
const report = await convertPptxToPng(pptx, {
  slides: [1],
  width: 1920,
});
 
const firstSlide = report.slides[0];
if (firstSlide) {
  await writeFile("slide-1.png", firstSlide.png);
}

Each conversion returns slides, diagnostics, and supportCoverage. Check diagnostics when content is skipped or rendered with a fallback.
