We are using FrameMaker 2017 for a document that typically publishes to PDF but now must publish to HTML, as well.
We've resolved most of the mapping issues, but we continue to struggle with the output graphics, particularly with equations. Equations are converted to images in the HTML output (and in most non-PDF outputs I've tested), but the images are so blurry and poorly rendered that they can't be used. In the Style Mapping settings, the JPEG resolution option only goes up to 100! I've tried multiple setting changes and it only gets worse, not better.
Is there some way to increase the equations output resolution or is this a known issue for which Adobe has no solution yet?
Are you using the legacy FM Equations feature, or XML (MathML, MathFlow, MathType)?
As far as I know, the legacy Eqs always export to HTML as raster images, which is rather less than ideal.

Thanks for the response! It must be the legacy version (we go to Insert > Equations instead of Insert > MathML Equation). This is definitely less than ideal. We can work with images, but they need to be decent quality so people can read them. Is there no way to improve the resolution in the output? Or a way to easily convert the legacy equations to MathML?

re: Is there no way to improve the resolution in the output?
As I recall, there's a choice of raster formats, and some of the workflow options might allow a higher possible resolution, but equations as raster is just sad, in an era where their semantics and text representation would ideally just be preserved into the deliverables.
Converting FM Eqs to XML has been asked about before, but I'm not quickly seeing a solution.
There may also be a further issue with MathFlow in FM, as FRMAKER-11189 seems to still be open.
If I needed to deal with equations these days, I'd probably rely on an external MathML editor, and import whatever XML, or at least SVG, output from that seemed to be satisfactory.

Just playing with the matter a bit, I tried using the OpenOffice Math (.odf) editor. The user interface is very much like FM's Equation Editor, but with more features. As to getting an equation into FM from that (and perhaps from other MathML editors):
