Why this HTML workflow breaks on iOS

Telegram can deliver HTML attachments, exports, reports, and AI-generated files. On iPhone, the attachment may need a dedicated viewer to become a readable 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 Telegram workflow

Open the Telegram file, share or save it to Files, choose Html Preview, and render the HTML locally on iPhone or iPad.

What to check before opening

Telegram: For reliable preview, use self-contained HTML. Neighboring CSS, scripts, images, anchors, or other local pages may not resolve as a project.

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.
