HTML & Markdown Viewer vs HTML Web Preview

Artifact Viewer opens AI-generated HTML, Markdown, and ZIP files — including JavaScript, CSS, Mermaid diagrams, and GFM tables — through a private local server for full compatibility. * AI Artifact Ready: Import from ChatGPT, Files, WeChat, Mail, and other apps. * Full Local Rendering: Everything runs on-device through a private HTTP server. * PDF & PNG Export: Export any view as PDF or the current screen as PNG. * ZIP Support: Extract and browse ZIP bundles with entry switching. * Markdown Viewer: Built-in template with Mermaid and table support. * Private by Design: All content stays in the app sandbox. Built for developers, researchers, and AI users who work with rich HTML artifacts.

Open your web projects on iPhone and iPad. HTML Web Preview opens a folder of HTML and its related files, with JSON and source available alongside the page. Explore your own study materials, web documents, small tools and prototypes on your device. • Open a project folder: keep HTML, CSS, JavaScript, images and JSON together with their file structure intact. • Keep your originals: the app does not modify selected files or folders. Switch between formatted JSON and original text, and refresh after editing files in another app. • Preview before running: folders open with page JavaScript disabled. Review the contents and run only projects you trust. A separately confirmed compatibility mode is available for some web features. • Adjust the view: collapse the controls, use the current device screen, or select a fixed or custom resolution. Zoom the page as in a browser to adjust text and element sizes, line wrapping and layout. Resolution settings do not reproduce every feature of a device. • Inspect errors: distinguish missing files from page errors and check the project activity log. Before you begin Projects can work offline when all required files are stored on your device and no external services are needed. Cloud downloads, external web resources and ads may require internet access. ZIP extraction, file editing, server-side programs such as Python, PHP or Node.js, project builds and download management are not supported. Open the finished web output folder for projects that need a build step. Page inputs and runtime state are not permanently saved and may reset when a project closes or restarts. Read-only access does not block every form of external communication. Run only trusted projects without sensitive files. The version 1.3 interface supports 15 languages: Korean, English, Japanese, Simplified and Traditional Chinese, German, French, Spanish, Brazilian Portuguese, Arabic, Uzbek, Vietnamese, Thai, Hebrew and Serbian (Latin script). Your documents and code remain in their original language.
