How do I open a GitHub Copilot HTML file on iPhone or iPad?
Install Html 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, Safari, Mail, WeChat, WhatsApp, Telegram, iCloud Drive, Google Drive, or Dropbox gives you an HTML file, share it to Html Preview and read it immediately. 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 an HTML file from GitHub Copilot 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
Html Preview is the dedicated local viewer for .html, .htm, .xhtml; it avoids upload and converter workflows.
When not to use it
If you only have a normal web link, Safari is enough. Use Html Preview when the item is a local .html, .htm, or .xhtml file that iOS cannot preview cleanly.
If the file is Markdown instead
Use Md Preview, the companion iOS viewer for Markdown files, when this workflow produces Markdown instead of HTML.
Next action
Open the App Store listing, install the viewer, then return to the file and share it to Html Preview.
File situations covered
Use this as a quick match for the file type, source app, device, and question you have.
Best HTML viewer for iPhone: open local files from Files, ChatGPT, Mail, and downloads. Use Md Preview for Markdown.
The iOS gap this app solves

Focused viewer
No editor, project manager, account, or browser clutter.
Encoding support
Handles UTF-8, Windows-1252, and ISO Latin-1 files.
Private by design
No analytics, no uploads, and no tracking.
Made for AI-generated HTML reports
When ChatGPT, Claude, Gemini, Perplexity, Copilot, DeepSeek, Grok, NotebookLM, Safari, Mail, WeChat, WhatsApp, Telegram, iCloud Drive, Google Drive, or Dropbox gives you an HTML file, share it to Html Preview and read it immediately.
Save the HTML file from GitHub Copilot. Keep the original .html, .htm, .xhtml file available in Files, Mail, a browser download, or the source app.
Open the iOS Share Sheet
Save the GitHub Copilot HTML file, open it from Files, Downloads, Mail, or the source app, share it to Html Preview, and preview it locally on iPhone or iPad.
Choose the viewer
Choose Html Preview as the target viewer. It opens the file locally on iPhone or iPad for this workflow: open a GitHub Copilot HTML file.
Preview and check
GitHub Copilot: For reliable preview, use self-contained HTML. Neighboring CSS, scripts, images, anchors, or other local pages may not resolve as a project.
Why this HTML workflow breaks on iOS
GitHub Copilot can produce HTML files for IDE-generated previews, code suggestions, web snippets, and documentation pages. iOS can save those files, but users often need a focused local viewer to read the rendered result instead of raw file text.
The shortest answer
Install Html 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 GitHub Copilot workflow

What to check before opening
GitHub Copilot: For reliable preview, use self-contained HTML. Neighboring CSS, scripts, images, anchors, or other local pages may not resolve as a project.
Why local preview fits this job
Html Preview is focused on file preview. It avoids uploads, account setup, ad clutter, and heavy editing features when the user simply needs to read an HTML file now.
If you also receive Markdown files
AI and document workflows often produce both HTML and Markdown. Md Preview is the companion viewer for that file type.
