Hi. I can download free psd and convert to html and sale in themeforest ? excuse me for my bad english
If you have permission for the free template author, yes you can. You should ask license + permission the PSD author.
Almost certainly the license will say this is not allowed PLUS my guess is that 95% of ‘Free files” (PSD or otherwise) are not going to be good enough for here without some pretty substantial additions and editing
Free PSD are not so good for Envato marketpalces. In my opinion your items will be hard rejected. Have a good day
