Fine-tune your next post on the boat, plane, or train, and publish it when you're back online. - Browse your Apple Photos, drag images directly, or insert images into your blog post with the click of a button. MarsEdit uploads them all when you're ready to publish. - Avoid common browser-based problems like losing your edits by navigating to another page, poor spelling for lack of a spell checker, etc. - Perfect for professional bloggers and casual writers who don't want to mess around with clunky web-based interfaces. If you're lucky enough to have a Mac, nothing is more powerful or more elegant than MarsEdit. - Write in Rich Text "WYSIWYG" that will be converted automatically to HTML when you publish, or hand-tune the HTML in a syntax-highlighted code editor. Markdown fan? Write in Markdown in the HTML editor and see a live-preview of the HTML rendering in the preview window. - Compatible with macOS 10.15.4 or higher. Coming to the Mac from Windows? MarsEdit is similar to Live Writer, the popular Windows blog editor, but differs in some ways. Ask around and read MarsEdit reviews to decide if MarsEdit is right for you.
