About

OneOpen opens the files you receive from Files, Mail, and other apps. Everyday viewing stays free and local. FREE FILE VIEWING Open HTML and ZIP website packages as isolated mini apps. Read Markdown, PDF, Office and iWork documents, common images, audio, video, JSON, YAML, XML, CSV, source code, and text. Search and edit common text formats in a separate copy; your original remains untouched. Recents and widgets put your files within reach. ADVANCED FORMATS Advanced Access unlocks specialized previews: 3D models, RAW and design images, fonts, certificates, property lists, email, subtitles, contacts, calendars, specialist archives and data, CAD and circuit files, and the binary inspector. Choose an annual subscription or a one-time lifetime purchase; both unlock the same features. PRIVACY AND HTML SAFETY OneOpen has no account, ads, analytics, or document uploads. Non-HTML previews stay offline. Imported HTML and ZIP websites may run JavaScript and connect to HTTPS/WSS servers in an isolated WebKit store. Switch to offline mode or Safe Preview at any time; HTTP, embedded frames, unexpected navigation, and access to other local files remain blocked. Webpage code may contact third-party servers when you allow network access.
