HTML Opener vs HTML Web Preview

When you open an HTML file in the iPhone Files app, iOS just dumps lines of raw code on your screen. Buttons do not work, styles break, and Safari cannot open local file links. HTML Opener fixes that. It runs your local HTML, CSS, JavaScript, and images in a real WebKit browser directly on your iPhone and iPad. No Mac, no terminal, and no local server required. WHAT IT SOLVES - Files app dumps raw code and text on screen instead of rendering the webpage - Safari has no address bar option to open local file:// links - Opening a single file breaks CSS styles and image assets in neighboring folders - Setting up a local server on your computer just to check mobile layout is tedious REAL WEBKIT BROWSER RENDERING Built on iOS's native WKWebView engine. Buttons, forms, CSS styling, canvas animations, and modern JavaScript run exactly as they would in Safari. OPEN AN ENTIRE PROJECT FOLDER Select a folder containing style.css, script.js, and an images directory alongside your HTML file. All relative file paths resolve automatically with zero broken images or missing styles. DESKTOP & MOBILE VIEW TOGGLE Switch between phone layout and 1024px desktop view with a single tap. Review horizontal dashboards, data tables, and desktop web tools without broken layouts. FULLSCREEN MODE Hide navigation bars and margins to give your web content the entire display. Web apps and tools feel like installed native apps. FOUR SIMPLE ACTIONS 1. Open a local file or folder 2. Quick Switcher to jump between recent projects 3. Auto-launch your primary tool as soon as the app starts 4. Clear cache, toggle dark theme, and customize display options WHO IT IS FOR - Anyone stuck when iPhone opens HTML as raw code - Developers and designers testing web prototypes on actual iOS hardware - Anyone running self-built dashboards, calculators, or tools on the go - Students learning web development who want instant mobile testing PRO (ONE-TIME PURCHASE, NEVER A SUBSCRIPTION) Removes ads completely.

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.
