MarsEdit continues to evolve over the 15+ years since it debuted. Here are some of the most-loved features of the app:
Rich and Plain Text Editing
MarsEdit's editor switches easily from Plain to Rich Text, so you can work in whichever format you prefer. Love Markdown? MarsEdit can preview it and convert it to HTML if needed.Advanced WordPress Support
MarsEdit knows about featured images, post formats, and multiple authors. It even supports adding custom fields that appear right in the post editor window.
Focused on Writing
With full support for Apple's standard full-screen mode, and a custom "Typewriter Mode" to keep text centered vertically, you can work on your blog with minimal distraction.
A Real Media Maven
Quickly scan your Apple Photos, Aperture, or Lightroom, and insert images into your blog post with the click of a button. MarsEdit uploads them all when you're ready to publish.Enhanced Blog Archiving
For most blog services, MarsEdit is now able to download the entire history of published posts and pages, so a backup of all your writing is stored safely on your Mac.
Automatic Preview Template Generation
Preview your posts as you write them, just as they'll appear when published on the web. A baseline template is easily created and can be fine-tuned by hand if desired.
Fast Live Previews
Native filters for Markdown, MultiMarkdown, and Convert Line Breaks run at lightning speed, converting your writing on the fly as you type.
Dazzling System Integration
MarsEdit Safari App Extension makes it easy to create new posts based on things you read on the web. Support for macOS standard autosave means never worrying about losing your work.
