OpenHTML: HTML & Markdown

ZIP, JSON & Local Preview

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Open HTML, Markdown, ZIP web projects, JSON and XML locally. Preview, diagnose, and export pages without accounts or tracking. 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 - Preview local pages with scripts and 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 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. 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.
