Why this HTML workflow breaks on iOS

When iOS does not preview an HTML attachment, AI export, saved page, or downloaded file cleanly, the user needs a small app that accepts the file and renders it as a 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 app to open HTML file searches workflow

Open the HTML file, tap Share, choose Html Preview, and keep the workflow focused on reading the file.

What to check before opening

If you also receive Markdown files, Md Preview is the companion app for .md, .markdown, .mdx, .rmd, and .qmd.

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.
