Why this HTML workflow breaks on iOS

OneDrive is common for Office documents, Outlook attachments, shared reports, and work exports. The file may sync to iPhone, but iOS still may not provide a clean rendered HTML 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 OneDrive workflow

Open the file in OneDrive or Files, tap Share, choose Html Preview, and read the rendered HTML locally on iPhone or iPad.

What to check before opening

If the OneDrive export includes an HTML file plus asset folders, keep the folder structure together 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.
