Open HTML files and ZIP websites on iPhone and iPad — completely offline. No account, no tracking, no ads. HTML Reader Offline turns your device into a portable library for local web content. Save a tutorial, a documentation site, an exported notebook or any .html / .zip bundle, then read it anywhere: on a plane, on the subway, or somewhere with no signal at all. WHY IT'S DIFFERENT • Truly offline. Files live on your device. Nothing is uploaded and no connection is ever required. • Single files or whole sites. Import one .html page, or a ZIP bundle with its CSS, scripts and images intact. • A private space per document. Each document loads in its own isolated storage area, so two tutorials never overwrite each other's saved state or progress. • Fits every screen. The interface adapts to the actual display — compact on a phone, spacious on an iPad or a folding phone's inner screen. READING THAT GETS OUT OF THE WAY • Automatic table of contents built from the page headings — jump to any section in one tap. • Full-text search inside the page, with a match counter and one-tap navigation between hits. • Bookmarks for the passages you want to return to. • Highlights in five colours, each with an optional note; they stay anchored to the text through font changes and rotation. • Adjustable font size, light / dark / sepia themes, and a subtle progress bar. • Reopens exactly where you left off. A LIBRARY YOU CAN ACTUALLY MANAGE • Folders with drag-and-drop, so documents stay organised. • Library-wide search: look across every document at once and land straight on the matching paragraph. • Reading statistics: total time, today's time, your daily streak, and a 7-day chart. • Backup and restore: export the entire library — documents, progress, bookmarks, highlights and settings — into one ZIP file, and bring it back whenever you need it. SHARE WHAT YOU'RE READING • Send a document to anyone as a single .html file, or as a ZIP bundle they can open in any browser or re-import into the app. PRIVACY, PLAINLY No sign-up, no analytics, no advertising, no third-party trackers. The app never makes a network request for you, and your files never leave your device. Tip Jar (optional): Settings → Tip Jar offers a one-time, voluntary tip. It unlocks nothing — every feature in the app is free for everyone. Have a question or an idea? The support link below reaches me directly.
