Evince vs ViewAnyFile.app

Evince is a free document viewer for Linux desktop users. It opens PDF, PostScript, DjVu, DVI, XPS, OXPS, and Comic Book Archive files, and can display supported documents as full-screen presentations. Interactive forms can be completed, including text fields and scrollable list boxes. For PDFs, Evince can add notes and text highlights; these annotations are limited to PDF files. SyncTeX synchronizes a TeX source file with its resulting PDF. Printing is documented for DVI, DjVu, PDF, PostScript, and TIFF. When opening a password-protected PDF, Evince prompts for its password. It is not a file editor. Some Linux distributions may need the relevant backend package to support every listed format. The project wiki recommends obtaining Evince through the user's Linux distribution and points to packages or source for other download options. The help site includes user documentation and directions for reporting application bugs.

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.
