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 Firefox Downloads 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.

Open the iOS Share Sheet
Save the Markdown download from Firefox, keep related asset folders with it, open the iOS Share Sheet, choose Md Preview, and preview the file 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 Firefox Markdown download.
Preview and check
Use this workflow for actual .md, .markdown, .mdx, .rmd, or .qmd files from Firefox. If the download is a ZIP, extract it first and keep asset folders beside the main file.
Why this Markdown workflow breaks on iOS
Firefox can save real Markdown files into iOS Downloads or Files, but iPhone preview often needs a focused local viewer when the goal is reading the formatted document instead of raw Markdown.
