How do I open a Markdown file on iPhone?

Short answer

Send the .md or .markdown file to your iPhone, tap Share, and choose HTML Keep. A single Markdown file opens directly in a rendered preview, and Markdown files inside a ZIP or file project open from the native file viewer.

What is happening

Markdown is common in README files, notes, documentation, and AI-generated instructions. A plain text preview can make headings, lists, code blocks, tables, and links harder to read on a phone.

The easy next step

Open the Markdown file with HTML Keep when you want a readable preview. If the Markdown sits beside images or other project files, keep those files together in the same ZIP so local links can resolve inside the project.

Open it with HTML Keep

HTML Keep treats Markdown as a native file preview: it renders the document for reading, keeps local project boundaries intact, and opens external links with the system.

• Open HTML from Files, Mail, AirDrop, and AI tools
• Keep ZIP project assets together
• Reopen pages from your local library
• Put favorite pages on the Home Screen

Best fit

• AI-generated pages, personal tools, class demos, and small reports fit naturally.
• ZIP projects work best when the HTML, CSS, JavaScript, and media stay together.
• Use HTML Keep as the mobile place to open, keep, and revisit local web pages.
