How to avoid img size tags on markdown when converting docx to markdown?

I'm converting docx files using pandoc 1.16.0.2 and everything works great except right after each image, the size attributes are showing as text in teh 

![](./media/media/image4.png){width="3.266949912510936in"
height="2.141852580927384in"}

So it shows the image fine in the md but also the size tag as plain text right behind/after/below each image. The command I'm using is:

pandoc --extract-media ./media2 -s word.docx markdown -o exm_word2.md

I've read the manual as best I can but don’t see any flags to use to control this. Also most searches are coming up where people want to have the attributes and control them.

Any suggestions to kill the size attributes or is my markdown app (MarkdownPad2 - v-2.5.x) reading this md wrong?

There are two ways to do this: either remove all image attributes with a Lua filter or choose an output format that doesn't support attributes on images.

Output format

The easiest (and most standard-compliant) method is to convert to commonmark. However, CommonMark allows raw HTML snippets, so pandoc tries to be helpful and creates an HTML <img> element for images with attributes. We can prevent that by disabling the raw_html format extension:

pandoc --to=commonmark-raw_html ...

If you intend to publish the document on GitHub, then GitHub Flavored Markdown (gfm) is a good choice.

pandoc --to=gfm-raw_html ...

For pandoc's Markdown, we have to also disable the link_attributes extension:

pandoc --to=markdown-raw_html-link_attributes ...

This last method is the only one that works with older (pre 2.0) pandoc version; all other suggestions here require newer versions.

Lua filter

The filter is straight-forward, it simply removes all attributes from all images

function Image (img)
  img.attr = pandoc.Attr{}
  return img
end

To apply the filter, we need to save the above into a file no-img-attr.lua and pass that file to pandoc with

pandoc --lua-filter=no-img-attr.lua ...

Use -w gfm as argument in the command line to omit the dimensional of Images.

You could write a filter to do this. You'll need to install panflute. Save this as remove_img_size.py:

import panflute as pf


def change_md_link(elem, doc):
    if isinstance(elem, pf.Image):
        elem.attributes.pop('width', None)
        elem.attributes.pop('height', None)
    return elem


if __name__ == "__main__":
    pf.run_filter(change_md_link)

Then compile with 

pandoc word.docx -F remove_img_size.py -o exm_word2.md
