If you already have a Markdown file from Files, AirDrop, iCloud Drive, this guide shows the shortest local preview path on iPhone or iPad without uploading the file.
Quick answer
Install Md Preview, open the file from Files or the iOS Share Sheet, and preview it locally on iPhone or iPad.
Open a Google Chat Markdown file on iPhone with Md Preview. Render notes, code, links, images, and tables locally. No upload.
How do I open an MD file from the Files app on iPhone or iPad?
Install Md Preview, open the file from Files or the iOS Share Sheet, and preview it locally on iPhone or iPad. When ChatGPT, Claude, Gemini, Perplexity, Copilot, DeepSeek, Grok, NotebookLM, Obsidian, Notion, GitHub, Mail, iCloud Drive, Google Drive, or Dropbox gives you a Markdown file, open it in Md Preview for a clean rendered view. No subscriptions. No in-app purchases. No ads.
When this is the right iOS fix
Use this route when the file already exists and you need a reliable preview path on iPhone or iPad.
Best-fit search intent
You have a Markdown file from Files, AirDrop, iCloud Drive and iOS shows an icon, raw code, or an unreadable preview.
Native iOS path
Start from Files, Mail, Safari downloads, AirDrop, a cloud drive, or the source app, then use Share or Open In.
Viewer role
Md Preview is the dedicated local viewer for .md, .markdown, .mdx, .rmd, .qmd; it avoids upload and converter workflows.
When not to use it
If raw text is enough, Files can show many .md files. Use Md Preview when you need rendered Markdown, code, math, tables, or Mermaid on iPhone or iPad.
If the file is HTML instead
Use Html Preview, the companion iOS viewer for HTML files, when this workflow produces HTML instead of Markdown.
Next action
Open the App Store listing, install the viewer, then return to the file and share it to Md Preview.
File situations covered
Use this as a quick match for the file type, source app, device, and question you have.
Md Preview fixes .md locally when Files/Quick Look shows raw text on iPhone.
The iOS gap this app solves
AI chatbots, GitHub projects, note apps, and documentation tools produce Markdown files every day. On iPhone and iPad those files are often hard to read without a dedicated viewer.
Full Markdown preview
GFM tables, task lists, footnotes, links, and strikethrough.
Technical content
Code highlighting, LaTeX math, and Mermaid diagrams.
Private by design
No analytics, no uploads, and no tracking.
Made for AI-generated Markdown
When ChatGPT, Claude, Gemini, Perplexity, Copilot, DeepSeek, Grok, NotebookLM, Obsidian, Notion, GitHub, Mail, iCloud Drive, Google Drive, or Dropbox gives you a Markdown file, open it in Md Preview for a clean rendered view.
Save the Markdown file from Files, AirDrop, iCloud Drive. 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
Long-press the Markdown file, choose Share, send it to Md Preview, and read the rendered version locally.
Choose the viewer
Choose Md Preview as the target viewer. It opens the file locally on iPhone or iPad for this workflow: open an MD file from the Files app.
Preview and check
Use this for files received through AirDrop, saved from chat apps, or synced from iCloud Drive.
Why this Markdown workflow breaks on iOS
The Files app can store .md, .markdown, and .mdx files, but tapping them often gives plain text instead of a useful 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 Files, AirDrop, iCloud Drive workflow
Long-press the Markdown file, choose Share, send it to Md Preview, and read the rendered version locally.
What to check before opening
Use this for files received through AirDrop, saved from chat apps, or synced from iCloud Drive.
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.
Can Apple Preview open Markdown files in iOS 26?
No. Apple's iPhone guide describes Preview as an app for opening and viewing PDF documents and images; it does not list Markdown as a supported Preview format.
For a local Markdown file, use Open With, Always Open With when available, or Share to Md Preview.
