I am using MikTeX with Windows 7. I have installed tex4ht using the package manager. The conversion of formulae are not ideal. Some formulae seem a bit choppy while others seem very horrible.

Example of Choppy-looking formula.

Is there a way to fix this?

Updated question

After the suggestion of michal.h21, the output looked a little bit better.

However the inline formulae needs a bit improvements. For example

enter image description here


enter image description here

Some \begin{array} equations also needs improvements.

for example - Look at the minus sign and size of u. enter image description here

I would like to point out in order to write the derivatives I am using a

\newcommand{\Dn}3{\frac{\text{d}^#1 #2}{\text{d}#3^{#1}}} % for n-th derivative

I don't know if this should make any difference or not.

This is the link to my code which was requested by Sebastiano.

    Can you add your code *.tex, please?

  • Maybe you should have a look at the available options (MathML, Other Options).

  • just use svg for math and everything will be just fine.

It seems that Miktex haven't updated the last fixes regarding default quality of images in tex4ht. It uses dvipng for the conversion now, and the quality got much better. There are also other alternatives, such as to use vector SVG images, or to use MathML with Mathjax library for rendering.

You can easily use the better methods in Miktex as well, using make4ht build files. Save the following code as mybuild.mk4:

Make:image("png$","dvipng -bg Transparent -T tight -D151  -o     ${output}  -pp ${page} ${source}")
Make:image("svg$","dvisvgm -n -p ${page} -c 1.4,1.4 -s ${source} > ${output}")

You can compile your file using

make4ht -ue mybuild.mk4 filename.tex

For the following nonsensical math sample:


  \left(-\frac{{h}^{2}}{2m}\delta-\frac{{e}^{2}}{4\pi} \right) = \theta

You will get the following png picture:

To get the svg image, you need to use small configuration file, mycfg.cfg:




It requires the output format for the pictures to be the svg format. You can request the config file in the compilation using

make4ht -ue mybuild.mk4 -c mycfg.cfg filename.tex

And this is the result. Note that it is blurred because it is screenshot from the browser, Stackexchange doesn't support SVG image upload. It looks better in the reality:

The last possibility is to use MathML with MathJax. Use the following config file, mathjax.cfg:


\Configure{@HEAD}{\HCode{\Hnewline<script type="text/javascript"


compile the document using

make4ht -uc mathjax.cfg filename.tex

This is the result:

enter image description here

You can try also other options for MathJax output, see MML_SVG and MML_HTMLorMML in the MathJax documentation. You can put those options in the configuration file after MathJax.js?config=. I think the MML_CMATH is preferred nowadays, but the other options may work better for you.
