A smoother media editing experience
Improved visual editingThe updated visual editor has improved speed, accessibility, and mobile support. You can paste into the visual editor from your word processor without wasting time to clean up messy styling. (Yeah, we’re talking about you, Microsoft Word.)
Edit images easilyWith quicker access to crop and rotation tools, it’s now much easier to edit your images while editing posts. You can also scale images directly in the editor to find just the right fit.
Drag and drop your imagesUploading your images is easier than ever. Just grab them from your desktop and drop them onto the editor.
Gallery previewsGalleries display a beautiful grid of images right in the editor, just like they do in your published post.
Do more with audio and videoImages have galleries; now we’ve added simple audio and video playlists, so you can showcase your music and clips.
Live widget and header previewsAdd, edit, and rearrange your site’s widgets right in the theme customizer. No “save and surprise” — preview your changes live and only save them when you’re ready. The improved header image tool also lets you upload, crop, and manage headers while customizing your theme.
