How it works

Save the source file

Save the Markdown file from LINE. Keep the original .md, .markdown, .mdx, .rmd, .qmd file available in Files, Mail, a browser download, or the source app.

Open the iOS Share Sheet

Open the LINE attachment, share or save it to Files, choose Md Preview, and read the rendered Markdown locally.

Choose the viewer

Choose Md Preview as the target viewer. It opens the file locally on iPhone or iPad for this workflow: open a Markdown file from LINE.

Preview and check

This helps when the LINE file contains headings, lists, code blocks, tables, links, math, or Mermaid diagrams.

Why this Markdown workflow breaks on iOS

LINE users can receive Markdown notes, AI summaries, prompts, and docs in chat. On iPhone, raw Markdown syntax is harder to read than a rendered preview.

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 LINE workflow

Open the LINE attachment, share or save it to Files, choose Md Preview, and read the rendered Markdown locally.

What to check before opening

This helps when the LINE file contains headings, lists, code blocks, tables, links, math, or Mermaid diagrams.

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.
