How do I open an HTML email attachment 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, 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.
The iOS gap this app solves
AI chatbots and web tools increasingly export reports as HTML files, but iPhone and iPad users often see a file icon instead of a readable page. Html Preview gives those files a reliable place to open.
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, 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.

How it works
Receive a file
Save or receive an .html, .htm, or .xhtml file from any app.
Share to Html Preview
Use the iOS Share Sheet or file picker.
Read instantly
The file renders locally in a fast iOS WebView.
Why this HTML workflow breaks on iOS
Invoices, newsletters, exported reports, and saved web pages can arrive as HTML attachments. iOS may show the attachment as a file instead of a readable page.
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 Mail, Gmail, Outlook workflow
Open the attachment, tap Share, send it to Html Preview, and preview the HTML file on your device.
What to check before opening
If the attachment came with a folder of images or styles, keep those files beside the HTML attachment before opening.
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 a 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.
