How it works
Save the source file
Save the HTML file from iOS file preview problem. 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 file, open the iOS Share Sheet, choose Html Preview, and render the HTML locally instead of treating it like an unknown attachment.
Choose the viewer
Choose Html Preview as the target viewer. It opens the file locally on iPhone or iPad for this workflow: fix an HTML file that iPhone cannot open.
Preview and check
Use this path for real .html, .htm, and .xhtml files. If the file came with asset folders, keep them beside the HTML file.
Why this HTML workflow breaks on iOS
The file is usually valid. The problem is that iOS does not always route standalone HTML files from Files, Mail, downloads, or chat apps into a clean rendered 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 iOS file preview problem workflow
Save the file, open the iOS Share Sheet, choose Html Preview, and render the HTML locally instead of treating it like an unknown attachment.
What to check before opening
Use this path for real .html, .htm, and .xhtml files. If the file came with asset folders, keep them beside the HTML file.
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.
