I have this in my ~/.emacs:

#+begin_src emacs-lisp
(setq luamagick
      '(luamagick
        :programs ("lualatex" "convert")
        :description "pdf > png"
        :message "you need to install lualatex and imagemagick."
        :use-xcolor t
        :image-input-type "pdf"
        :image-output-type "png"
        :image-size-adjust (1.7 . 1.5)
        :latex-compiler ("lualatex -interaction nonstopmode -output-directory %o %f")
        :image-converter ("convert -density %D -trim -antialias %f -quality 100 %O")))
(add-to-list 'org-preview-latex-process-alist luamagick)

(setq luasvg
      '(luasvg
        :programs ("lualatex" "dvisvgm")
        :description "dvi > svg"
        :message "you need to install lualatex and dvisvgm."
        :use-xcolor t
        :image-input-type "dvi"
        :image-output-type "svg"
        :image-size-adjust (1.7 . 1.5)
        :latex-compiler ("lualatex -interaction nonstopmode -output-format dvi -output-directory %o %f")
        :image-converter ("dvisvgm %f -n -b min -c %S -o %O")))
(add-to-list 'org-preview-latex-process-alist luasvg)
(setq org-preview-latex-default-process 'luasvg)
#+end_src

You can set 'org-preview-latex-default-process' to luasvg or luamagick

Best regards,

Juan Manuel
