Why this HTML workflow breaks on iOS

Apple Mail can receive HTML reports, receipts, exported pages, and AI-generated attachments. iOS can save the attachment, but the default preview may show a file instead of a rendered 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 Apple Mail workflow

Open the attachment in Mail, tap Share or Save to Files, choose Html Preview, and preview the HTML locally on your iPhone.

What to check before opening

For private mail attachments, local preview avoids uploading the file to an online converter just to read it.

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.
