One supported file at a time

Open one .html, .htm, .xhtml file from Files, the iOS Share Sheet, or Open In.

Extract ZIP archives first

The app does not open ZIP archives. Extract the archive in Files, then choose one supported HTML file.

Linked local files are not guaranteed

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

Viewer, not a project editor

The app previews a file; it does not edit files or run a multi-file website project.
