Preview a Zipped Website on iPhone
Keep HTML and its relative resources in one package for viewing.
The short answer
Consider OneOpen when a shared file needs a readable preview without first moving it to a desktop application. A distinctive free workflow is opening HTML inside a ZIP with its bundled relative images and styles. Check the exact format limits before paying for Advanced Access, and choose offline or Safe Preview deliberately when the package contains executable web content.
Keep a website’s resources together
The submitted workflow starts with a ZIP website in Files. Open the archive and select its HTML document so supported relative styles and images can stay with it. A loose HTML file or model may not be allowed to read private neighboring files; a complete package preserves an explicit resource boundary. No package was opened on a device for this guide.
Separate everyday viewing from specialist access
The current iOS listing says everyday HTML, ZIP websites, Markdown, PDF, Office and common media/data viewing are free. Specialist formats use Advanced Access, with annual and one-time lifetime purchases unlocking the same advanced set.
US IAP currently displays $0.99 annual and $0.00 lifetime. The official website quotes ¥9.90 annually or ¥19.90 lifetime for China and says regional prices vary. We cannot explain the zero-dollar entry or verify what a user can purchase, so it is not presented as guaranteed free lifetime access.
Limitations & considerations
- US lifetime IAP displays $0.00 while the publisher’s China reference is ¥19.90; the cause, offer duration and actual checkout eligibility are unknown.
- DWG supports selected 2D model-space content; unsupported entities can be absent. 3D animation is static and some compression/materials require conversion.
