Best alternatives to Viewer.Online in 2026
Everyone has hit this problem: someone sends a file with an extension you've never seen, or an old format your current software won't open, and you don't want to install a whole application just to check what's inside one file. Viewer.Online exists for exactly that moment — drop the file on the page and it renders a preview, no account or software required for a basic look. The service claims support for over 20,000 file formats and conversion between 1,500+ of them, spanning images (including RAW and PSD), documents (DOCX, PDF), video (MKV, MP4), audio, code and data files. Beyond simple viewing, it extracts metadata, hidden text, and archive contents, and files are processed in real time and automatically deleted afterward — nothing is retained. It grew out of FILExt.com, a file-extension reference site running since 2000, which explains the unusually broad format coverage. Partial previews and metadata extraction are free and unlimited; full previews and conversions require a paid account starting at $14.99/month for 500 previews, up to $24.90/month for 1,000 previews plus format conversion and priority processing.
