Why this HTML workflow breaks on iOS

JSFiddle snippets are easy to test in a browser, but a saved HTML demo can become awkward on iPhone when Files shows the source instead of the rendered result.

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 JSFiddle workflow

JSFiddle: Open one .html, .htm, .xhtml file from Files, the iOS Share Sheet, or Open In. For reliable preview, use self-contained HTML. Neighboring CSS, scripts, images, anchors, or other local pages may not resolve as a project.

What to check before opening

This path is for real HTML files or snippets you saved from JSFiddle. Keep linked resources available if the demo depends on them.

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.
