About File Viewer
This free file viewer online opens almost any file on one page. Drop in a file and it picks the right viewer by itself, whether it is a PDF, a Word document, a spreadsheet, a photo, a ZIP archive or a video. Everything runs inside your browser, so the file is never uploaded. You do not need to install anything.
Use it when someone sends you a file and your phone or office computer has no app for it. It helps with unusual attachments from email or WhatsApp, a RAR you cannot extract, a PSD from a designer or a 3D model for printing. If the type is unknown, the page still shows the first bytes of the file in a hex view.
How to use File Viewer
- Select or drop the file you want to open.
