Viewer – HTML & File Viewer

Open web pages that actually run — with JavaScript — plus PDFs, Office files, code, Markdown, JSON, CSV and zips. Everything stays on your device.

Viewer opens almost any file on your iPhone and iPad — and shows it the way it's meant to look.

WEB PAGES THAT ACTUALLY RUN Most previews show HTML with JavaScript turned off. Viewer runs it: scripts, modules, canvas, animations and local data all work. Open a whole folder or a zip of a website and its styles, scripts and images load too.

TOOLS FOR THE CURIOUS • View the page source, with syntax colours • A JavaScript console with errors, warnings and logs — and a prompt to run your own code • Find on page • Request the desktop or mobile version • Save as PDF or print

CODE, MARKDOWN, JSON AND CSV • Syntax colours and line numbers for nearly 200 languages • Markdown rendered like a great README, with tables, task lists and code blocks • JSON as a tree you can expand, collapse and copy from • CSV and TSV as a real table with a pinned header row

DOCUMENTS AND MEDIA • PDFs with page thumbnails, search and password support • Word, Excel, PowerPoint, Pages, Numbers, Keynote and RTF • Images with pinch and double-tap zoom • Video, audio and 3D models • A clean text view for anything else

MADE FOR iPHONE AND iPAD • Open files from the Files app, iCloud Drive, USB drives and other apps' share sheets • Recent files and pins, so what you need is one tap away • Sidebar layout on iPad, keyboard shortcut ⌘O to browse • Light and dark mode

PRIVATE BY DESIGN No accounts. No tracking. No data collected. Your files never leave your device.
