OpenHTML is a private, on-device viewer for HTML, Markdown, ZIP web projects and source files on iPhone and iPad. Open files from Files, Mail, chat apps, AI tools or Safari. Preview pages offline, inspect what went wrong when a file does not render, and export finished pages when you need a clean copy. What you can do: - Open .html, .htm, .xhtml and Markdown files - Import ZIP archives and multi-file web projects - Render LaTeX math in Markdown offline, with no scripts - Preview local pages with network access off by default - Diagnose missing files, blocked resources and JavaScript issues - View JSON, XML and source files with a code-friendly reader - Export full pages to PDF or long images with OpenHTML Pro - Keep selected files in your OpenHTML folder in iCloud Drive and open them on your other devices with OpenHTML Pro Private by default: OpenHTML has no accounts, no analytics and no ads. Files are copied into the app's private storage and stay on your device unless you add them to your own OpenHTML folder in iCloud Drive. Remote resources stay blocked unless you choose to allow them for a trusted document. OpenHTML is designed for developers, students, researchers, writers and anyone who receives HTML reports, AI-generated pages, saved webpages or packaged web projects and wants to inspect them safely on iOS.
