Preventing Word-to-PDF Acrobat converter from converting image text into editable text

[lucas0150]

Hello. 

I use Acrobat regularly to convert Word documents to PDF files, and my documents often contain JPEG graphs that I paste from.MATLAB. I'd like to know how I can prevent the Acrobat converter from converting my graphs' axis titles and axis ticks into editable text. In other words, I want Acrobat to transfer the JPEG images from the .docx file to the.pdf file without converting any part of the image into editable/searchable text (although I do want the remainder of the text in the document to be unaffected). As things stand, Acrobat is converting my JPEG graphs' axis titles and ticks into tiny characters: 

I could simply increase the size of the axis titles and ticks using Acrobat's PDF text editing features, but I happen to have over 70 similar graphs with the same problem, so that's out of the question. Please help!

JPEG data in your Word file stays JPEG. So, this does not seam to be JPEG.
