Images of LaTeX equations exported to Word are of varying quality

I have a document with LaTeX equations in Confluence that I need to export to Word.

The LaTeX images are not automatically inserted in the Word document. However, they are placed in the temp folder in order. So, my original solution was, after export, to individually insert each image in the Word document from the temp folder.

I now have a document close to 200 pages long with more than 1000 LaTeX equations. I am now trying to insert the LaTeX images (.png) that are created during export into the Confluence page because any .png file should automatically be inserted in a Word document.

When I export a Confluence page with images of LaTeX equations (instead of actual LaTeX), the quality of the images varies, and not even in a consistent way. Some images look great, some are shrunk, some are stretched. And it isn't the same every time I export. So, I can export the same page numerous times and not know which images will look good and which ones will be altered.

How do I fix this? It is a very time consuming problem, and I appreciate your help.

Thanks!
