Each of the following were tested by pasting the contents of a document from LibreOffice 3.0. The document contained one embedded image.
- CKEditor - maintains most formatting (including coloring and indentation), but loses centering and images
- TinyMCE - preserves coloring and indentation, but not centering or images
- Visual editor - preserves only text; loses all formatting
- this extension is still under development, so the pasting may be improved later
- MeanEditor - not quite WYSIWYG, but still preserves coloring, indentation, and centering
- WikEd: graphical but not necessarily WYSIWYG; couldn't find a demo page
