Small on purpose.

Plain files, nothing else

Open and save ordinary .md and .markdown files wherever you keep them. No library to import, no account, no format that locks you in.

Two views, one shortcut

Press ⇧⌘P to flip between Source and Preview. Pick which one new documents open in.

A toolbar for when you forget

Bold, italic, links, headings, lists, quotes, inline code and code blocks are one click away. Counts for words, characters, reading time, line and column sit at the bottom.

Export and print

Save TXT, RTF or HTML from the File menu. Print and choose Save as PDF. RTF opens in Word and Pages.

Pictures next to your file

Relative images show up in the preview. The first time, macOS asks you to allow the document's folder, and remembers your answer.

Light, dark or system

Follow your Mac or pick an appearance of your own. Code blocks and diagrams switch with it.

Privacy, in one line.

miniMark collects nothing. No accounts, no analytics, no tracking.

Read the privacy policy, which is short.

Questions.

What is miniMark?

A small, native Markdown editor for Mac. It opens .md and .markdown files, lets you edit them as plain text, and shows a clean rendered preview.

Which Macs does it run on?

Macs with Apple silicon running macOS 14 Sonoma or later.

Does it collect my data?

No. There are no accounts, no analytics and no tracking, and nothing you write is sent to anyone. Your files stay where you save them.

What Markdown does the preview support?

Headings, bold, italic, strikethrough, links, images, lists, task lists, tables, quotes, code blocks with highlighting, footnotes, LaTeX math, and Mermaid diagrams.

How do I export a file?

Use File, Export for TXT, RTF or HTML. Use File, Print and choose Save as PDF for a PDF. RTF files open in Word and Pages. Math and diagrams appear in HTML and PDF; the RTF export keeps math as its source text.

Why does it ask for access to a folder?

The Mac only lets an app read files you have allowed. When your document links to pictures in its folder, miniMark asks once so it can show them in the preview.
