There are also online editors , with much smaller features than the previous ones, but with the advantage of not requiring any type of installation on the PC. Among the online publishers are: MarvinSketch, JME and Molview
Molview
Molview is an advanced java-based chemical editor that has the option of saving the work done as an image.
JME Molecular Editor
Simple java-based molecular editor, widely used on this website. This editor combined with small scripts written in java, allows to create interactive exercises.
