emf-converterEMF and WMF to PNG or SVG

A TypeScript library with no runtime dependencies. Runs in the browser, in Web Workers and in Node.js.

EMF, EMF+ and WMF

Reads Enhanced Metafiles, including embedded EMF+ (GDI+) records, and 16-bit Windows Metafiles. The format is detected from the file contents.

PNG output

Shapes, raster operations, brushes and clipping follow Windows GDI and GDI+ rasterisation. Output is tested against images rendered by Windows.

SVG output

Produces SVG markup, a data URL, a node tree for React or another createElement factory, or generated JSX/TSX component source.

Live demo

Select or drop an .emf or .wmf file. The file is converted in your browser and is not uploaded anywhere.

Example

ts

import { convertMetafileToDataUrl, convertMetafileToSvg } from 'emf-converter';

const buffer: ArrayBuffer = await file.arrayBuffer();

const png = await convertMetafileToDataUrl(buffer); // "data:image/png;base64,..."
const svg = await convertMetafileToSvg(buffer); // "<svg ...>...</svg>"
