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 or change the display area using mobile, tablet and computer aspect ratios. Aspect ratios 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 1.2 interface supports Korean, English, Japanese, Simplified and Traditional Chinese, German, French, Spanish and Brazilian Portuguese. Your documents and code remain in their original language.
