Why this HTML workflow breaks on iOS

.htm files are HTML files with an older extension. iOS can store them, but tapping the file from Files, Mail, or a cloud drive may not create a clean preview.

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 .htm files workflow

Save the .htm file, open the iOS Share Sheet, choose Html Preview, and read the rendered page locally.

What to check before opening

If the .htm file references images or styles, keep those assets beside the file 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 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.
