In their own words
Universal File Opener
Universal File Opener is an offline viewer and editor for supported files on Android and Windows. Its tools cover PDFs, Office documents, spreadsheets, presentations, images, archives, text, code, data, audio, and video, with available capabilities varying by platform and format. The listing includes 214 formats, archive, Office, and code previews, and in-file search. Reading supported files is free without a file-count limit, expiry, or watermark, though individual formats have size and compatibility limits. Files are processed on the device: Android does not request INTERNET permission, and the Windows app makes no network connections of its own. The apps have no advertising, app analytics, or Krauq account requirement. Android can read English text from scans using offline OCR. Files can be opened through Android sharing or file-picker features, or Windows dialogs and drag and drop; cloud providers handle their own downloads and syncing. Android Pro costs $1.99 a month or $9.99 a year. The listed lifetime option costs $5,029.99, paid once.
ViewAnyFile.app
ViewAnyFile.app is a browser-based viewer and converter for documents, spreadsheets, images, 3D models, CAD files, audio, video, code and databases. Its FAQ lists more than 200 supported formats and more than 40 conversion pairs. The product is described as a progressive web app for phones, tablets and desktops, with browser installation and offline support. Most processing happens in the browser, and client-side conversions have no limits. Legacy DOC, PPT and XLS conversions briefly use a server; server-side document conversions have a 25 MB limit. Client-side files are discarded when the tab closes, while server-processed files are purged within 60 seconds. The FAQ lists Chrome, Firefox, Safari, Edge, Brave and Opera, and recommends Chrome or Edge for formats that rely heavily on WebAssembly. The free core includes viewing, batch processing and client-side conversion without signup. A Pro plan is described as available soon at $9.99 a month. The service is not a certified HIPAA Business Associate.
