Media File Viewer – See documents and media with the correct type

When you open files on large document sites, links often have wrong or generic types (like “application/octet-stream”). The browser then doesn’t know if something is a text file, image, or video, so it may download it, show a blank page, or fail to play it.

Media File Viewer fixes that. It detects the real file type by reading the file’s content (magic bytes), then lets you open or preview the file with the correct type so you can view or play it properly.

What it does

1. Detect the real file type

Click “Determine File Type of This Page” while you’re on a file or document page. The extension fetches the beginning of the file and checks its magic-byte signature (the same idea as the file command). It doesn’t rely only on the URL or the server’s Content-Type, so you get the actual format.
