Support & User Guide

Getting help

The quickest way to reach a human is the contact form — or email support@quickmarkmd.com directly. For bug reports, please tell us your operating-system version, your QuickMark version (on Mac: QuickMark → About QuickMark; on iPhone or iPad: Settings → About), and — if you can — a sample .md file that reproduces the problem.

Opening & creating files

On Mac. Double-click any .md file to open it, or drag it onto QuickMark. To make QuickMark the default for Markdown files, right-click a .md file in Finder → Get Info → Open with: choose QuickMark → Change All…

On iPhone & iPad. Open QuickMark and start a new document from the home screen, or open an existing file from the Files app or from any app that can share a file. Your recently opened documents are listed on the home screen so you can jump back in.

Editing & saving

Type directly in the Editor or Split view. On Mac, QuickMark also refreshes automatically when you edit the same file in another app, so the preview always reflects what's on disk. On iPhone and iPad your changes are saved automatically as you type.

View modes

QuickMark has three ways to look at a document:

• Editor — the raw Markdown, in a clean monospace font.
• Split — editor and live preview side by side, scrolling in sync (Mac and iPad).
• Preview — the fully rendered document.

iPad opens new documents in Split by default; iPhone toggles between Editor and Preview. On Mac you also get an outline sidebar built from your headings, so you can jump around long documents quickly.

Quick Look on Mac

Select a .md file in Finder and press Space to preview it — fully rendered, with your themes — without opening the app. If Space still shows the plain-text system preview, another Quick Look extension is taking priority: open System Settings → General → Login Items & Extensions → Quick Look, uncheck the competing extension, and try again.

Save to QuickMark (iPhone & iPad)

From almost any app — Safari, Notes, Mail — use the Share button and choose Save to QuickMark. The shared text or link becomes a new .md file, and you pick where to save it.

Tabs

Keep several documents open at once. Mac and iPad show tabs across the top of the window; iPhone has a tab switcher. Open as many as you like — reorder them, drag a tab out into its own window, and reopen one you just closed.

Find in page

On Mac and iPad, search within the current document to jump between matches. Search is accent-insensitive — typing bi will also find bị — which is handy for many languages.

Markdown features

QuickMark renders the Markdown you already know, plus the extras writers reach for:

• GitHub Flavored Markdown — tables, task lists, footnotes, strikethrough, and automatic links.
• Math equations (inline and display) and Mermaid diagrams (flowcharts, sequence, and more).
• Callouts, ==highlight==, emoji, [[wiki links]], and YAML front matter.
• Syntax-highlighted code blocks for dozens of languages — hover (or tap) a block to copy it.

Themes & appearance

Pick a reading theme (Default, Docs, Notion, Essay, Terminal, or Minimal) and a code theme for syntax highlighting — all built in. QuickMark follows your system Light / Dark setting automatically, and on iPhone and iPad you can force Light or Dark. You can also set the editor font size. Find these in Settings (on Mac, QuickMark → Settings…; on iPhone or iPad, the gear icon).

Exporting

Turn a document into a polished file you can send or print. On Mac, iPhone, and iPad you can export to PDF, HTML, Word (.docx), EPUB, PNG image, and rich text you can paste straight into other apps. Exports follow your current reading theme and font size.

Publish to Web

Share a document as a clean, read-only web page at a link like quickmarkmd.com/s/…. Choose a short link or a readable one, then update or unpublish the page anytime. Anyone with the link can read it (pages are unlisted and kept out of search engines), so treat a published link as shareable.

An optional account (Sign in with Apple or email) lets you manage your published pages across devices — it's never required to publish. You can update a page anytime, or unpublish it to take it offline. Your original .md file on your device is never affected.

Tip: for the full list of keyboard shortcuts, open Help → Keyboard Shortcuts (⌘/) inside the Mac app.
