## What is OpenHTML?

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.

### 1/5 — 下载时候免费

*2026-08-15*

下载收费！

**Developer response:** 您好,感谢反馈。OpenHTML 本体完全免费下载和使用,Pro 是可选的内购功能(如更多主题/高级导出等),免费版核心功能不受影响。如果您在使用中遇到具体问题,欢迎详细说明,我们会尽快协助。

### 4/5 — Lack of LaTax supporting

*2026-08-05*

Markdown reading lacks proper formula rendering; introducing LaTeX support should be a priority.

**Developer response:** Update: LaTeX formula rendering is now available in version 1.4.0! 🎉

Both inline `$…$` and block `$$…$$` formulas are supported, with fully offline rendering—no internet connection required.

Feel free to update to the latest version and give it a try. We’d love to hear your feedback!
