Tex To Png.md

The standalone class in LaTex allows to convert individual equations, tables, and figures into .png files. It does require ImageMagick to convert pdf to image and crop

Important Note: If you are using a \begin{table}, \begin{figure}, or \begin{equation}/$$ environments, you must add the preview option to the \documentclass command or else it will not compile. For tables, I just use the \begin{tabular}\end{tabular} environment instead and it works fine and I just use $\displaystyle$ for equations.
