Why this HTML workflow breaks on iOS

LINE users can receive HTML attachments, reports, saved pages, and AI-generated files in chats. iOS may store the file but still lack a focused 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 LINE workflow

Open the LINE attachment, share or save it to Files, choose Html Preview, and preview the HTML locally on iPhone or iPad.

What to check before opening

If the HTML was exported with images or CSS, keep the related files with the HTML 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.
