embed-images

embed image files in markdown as base64

Takes a markdown file with images referenced by file and embeds the image content as base64. Useful if you want to render standalone markdown files without serving or hosting individual image files. Currently only handles png files.

Add to your project with

npm install embed-images --save

Or install as a command line tool with

npm install embed-images -g

If you have a file example.md with

# this is a markdown file with an image

![png](example.png)

And call

embed-images example.md

You'll get

# this is a markdown file with an image

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==" />
