TeX4ht needs some extra memory, because it declares link destinations for all sections and for each cut page. > Now for the issue of losing links. > > I used this command > > make4ht -ulm default foo.tex "mathjax,htm,fn-in,4" Try make4ht -ulm draft foo.tex "mathjax,htm,fn-in,3" It will produce separate files for sections, but not for subsections. You should save a lot of memory and compilation time using this. Best regards, Michal
