How do I open a README.md file 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 README.md files 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.

How it works
Save the source file
Save the Markdown file from README.md files. 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
Save README.md to Files, share it to Md Preview, and read the rendered document locally with headings, links, code, and tables.
Choose the viewer
Choose Md Preview as the target viewer. It opens the file locally on iPhone or iPad for this workflow: open a README.md file.
Preview and check
If the README references local screenshots or assets, keep those folders beside the file before previewing.
Why this Markdown workflow breaks on iOS
README.md files often explain a project, AI export, or downloaded repository. On iPhone, raw Markdown makes setup steps and code harder to scan.
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 README.md files workflow
Save README.md to Files, share it to Md Preview, and read the rendered document locally with headings, links, code, and tables.
What to check before opening
If the README references local screenshots or assets, keep those folders beside the file before previewing.
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.
