36 free file viewers that need no software at all
The viewers let you open and check document files — Word .docx, Excel .xlsx, PowerPoint .pptx, PDF, Markdown, EPUB, .eml/.msg email, .vcf contacts and .ics calendars — in your web browser, with no dedicated software installed. No account and no app installation required: just drag and drop a file to see what is inside straight away.
Support goes well beyond office documents. It covers images and graphics such as Photoshop .psd, iPhone .heic photos, multi-page .tiff, .svg and AutoCAD .dxf drawings; development and data formats such as JSON, XML, CSV, YAML, INI, HEX, diff, logs and ZIP; archives and media such as TAR/GZ, torrent, CBZ, subtitles and M3U; and even .stl and GCode for 3D printing and .gpx GPS tracks — 36 formats in all, covering the files that are usually awkward to open.
Because all display processing runs inside your browser (client-side), the files you open are never uploaded to a server. You can check confidential documents and personal photos with confidence, and closing the page clears them from your browser’s memory as well. No sign-up and no uploads — use it with confidence.
