Why this Markdown workflow breaks on iOS

The Markdown file is usually valid. The problem is that iOS can store .md files but does not always provide a complete rendered Markdown preview for Files, Mail, downloads, or chat apps.

The shortest answer

Install Md Preview, open the file from Files, the Share Sheet, or the source app, and preview it locally. The app has no subscriptions, no in-app purchases, and no ads.

The iOS file preview problem workflow

Save the .md file, open the iOS Share Sheet, choose Md Preview, and render the document locally instead of treating it like an unknown attachment.

What to check before opening

Use this path for .md, .markdown, .mdx, .rmd, and .qmd files from ChatGPT, Claude, Gemini, GitHub, Obsidian, Notion, and Files.

Why local preview fits this job

Md Preview is focused on file preview. It avoids uploads, account setup, ad clutter, and heavy editing features when the user simply needs to read a Markdown file now.

If you also receive HTML files

AI and document workflows often produce both Markdown and HTML. Html Preview is the companion viewer for that file type.
