When this is the right iOS fix
Use this route when the file already exists and you need a reliable preview path on iPhone or iPad.
Best-fit search intent
You have an HTML file from ChatGPT HTML ZIP exports and iOS shows an icon, raw code, or an unreadable preview.
Native iOS path
Start from Files, Mail, Safari downloads, AirDrop, a cloud drive, or the source app, then use Share or Open In.
Viewer role
Html Preview is the dedicated local viewer for .html, .htm, .xhtml; it avoids upload and converter workflows.
When not to use it
If you only have a normal web link, Safari is enough. Use Html Preview when the item is a local .html, .htm, or .xhtml file that iOS cannot preview cleanly.
If the file is Markdown instead
Use Md Preview, the companion iOS viewer for Markdown files, when this workflow produces Markdown instead of HTML.
Next action
Open the App Store listing, install the viewer, then return to the file and share it to Html Preview.
