MarsEdit 4

Write, preview, and publish your blog.

Requires macOS 10.12 or higher. Read about what's new in MarsEdit 4.

Think Outside The Browser

Browser-based interfaces are slow, clumsy, and require you to be online just to use them. Browsers are perfect for reading web content, but not ideal for creating it. If you're serious about writing for the web, you need a desktop blog editor. If you're lucky enough to have a Mac, nothing is more powerful, or more elegant than MarsEdit.

Feature Overview

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.

Wildly Compatible

Works with WordPress,, Tumblr, TypePad, Movable Type, and any blog that supports a standard MetaWeblog or AtomPub interface.

Easy File Uploads

Attach images and files directly to your post, and MarsEdit will upload them when you publish.

Media at Your Fingertips

Quickly scan your Apple Photos, Aperture, or Lightroom, and insert images into your blog post with the click of a button.

Re-Blog It!

Enable MarsEdit's Safari extension. When you discover something cool on the web, start a new MarsEdit post with the click of a button.

Offline Freedom

Write when you want to, without an internet connection. Fine-tune your masterpiece on the boat, plane, or train, and publish when you get back online.

Perfect Previews

Let MarsEdit's live preview show you how your posts will look before you publish them. Use Markdown or another text filter? MarsEdit will preview that, too.
