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 Markdown Mermaid and math 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 Markdown Mermaid and math 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 the .md file, keep referenced assets nearby, open it with Md Preview, and inspect the rendered code, diagrams, formulas, and tables locally.
Choose the viewer
Choose Md Preview as the target viewer. It opens the file locally on iPhone or iPad for this workflow: preview Markdown code, math, and Mermaid.
Preview and check
Use this for AI specs, GitHub docs, technical notes, and Mermaid-heavy Markdown drafts.
Why this Markdown workflow breaks on iOS
Technical Markdown from AI tools, docs, and repos often mixes code blocks, math, and Mermaid diagrams. Raw text hides the structure that matters.
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 Markdown Mermaid and math files workflow
Save the .md file, keep referenced assets nearby, open it with Md Preview, and inspect the rendered code, diagrams, formulas, and tables locally.
What to check before opening
Use this for AI specs, GitHub docs, technical notes, and Mermaid-heavy Markdown drafts.
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.
