OneMarkup: File Viewer

File Viewer & HTML Apps

Free · Designed for iPad. Not verified for macOS.

Preview most files locally, or run trusted HTML and ZIP packages as isolated mini apps. Open and inspect the files people actually send you—from Files, Mail, WeChat, and any app that shares documents. Ordinary file preview, search, and editing stay on your device, with no account, ads, analytics, tracking, or in-app purchases. PREVIEW MORE FILES • PDF, common and modern image formats including WebP and AVIF, Office/iWork, audio/video, and USDZ with iOS system controls • Complete ZIP website exports with index.html plus local CSS, images, fonts, and media • CBZ comics, ZIP-compatible package contents, GLB structure, fonts, certificates, property lists, email, source files, and unknown binaries READ AND EDIT Read Obsidian-style Markdown with a table of contents, heading jumps, tasks, callouts, footnotes, frontmatter, tags, and wide tables. Edit text-based formats through a Files-visible working copy while the original stays untouched. TRUSTED HTML MINI APPS HTML and ZIP websites open as isolated trusted-network mini apps by default: JavaScript and package assets can run, while network access is limited to HTTPS/WSS. Switch to Offline Mini App or Safe Preview at any time. HTTP/FTP, embedded frames, unexpected in-view navigation, and arbitrary access to other local files remain blocked. Webpage code can still contact third-party servers or send information you enter when its own logic requests it. QUICK ACCESS Recent files automatically appear in widget choices. Add multiple OneMarkup widgets, then choose a different file, name, and icon for each—including HTML mini apps. Small files are kept as local copies by default so source permissions cannot strand a shortcut.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

• HTML and ZIP websites now fill the screen, hide the status bar by default, and use plain Back and More icons with no button rings. • Every recent file is available to widgets; each widget can choose its own file, name, and icon. • Cold widget launches go straight to the file without flashing the app home screen. • Files up to 100 MB are copied into Imports by default so Recents keep working; this can be disabled in Settings. • Redesigned the World Clock, Focus Timer, and Memory Match mobile HTML mini apps.
