Why convert PNG to JPG?

JPG is ideal for photographs and social visuals where smaller sizes improve load times and engagement. Auto-Fix removes the manual export loop and ensures consistent color profiles.

Set background for transparency

If your PNG contains transparency, pick a brand color—or let Auto-Fix apply a smart background—to avoid unwanted halos or fringing in the final JPG.
