# pdf-to-png

Render a PDF to a PNG, useful for generating thumbnails. Uses [`electron-spawn`](https://github.com/maxogden/electron-spawn) and [`pdf.js`](https://mozilla.github.io/pdf.js/), so it doesn't require any image processing libraries. Supports a custom scale factor. Currently only renders the first page.
