OpenAnyFile
You have a EMF file and nothing on your machine will touch it. Here is what the format actually is, and how to read one in about four seconds without installing anything.
Enhanced Metafile is an image format developed by Microsoft, first appearing in 1993. It is normally produced by Office charts, Visio, CAD exports.
Stores device-independent vector drawing commands that Windows replays through GDI. Pasting an Excel chart into Word normally creates one, which is why the chart stays sharp when the document is zoomed or printed.

OpenAnyFile routes .emf to its progressive image decoder, which renders the picture drawn natively if your browser ships a decoder for this codec, and a full byte-level inspection with the detected signature if it does not.
Viewing, inspecting and verifying. You get the picture drawn natively if your browser ships a decoder for this codec, and a full byte-level inspection with the detected signature if it does not. File details, exact byte size and the detected signature are always shown.
Guaranteed rendering. Whether the picture draws depends on whether your browser ships a decoder for this codec; when it does not, you still get the full byte-level inspection instead of an error.
Most online viewers work by sending your file to their server, processing it there, and leaving a copy behind on infrastructure you do not control. OpenAnyFile does not. Your .emf file is read through the browser's local File API and decoded by JavaScript and WebAssembly running on your own machine. There is no upload step and no server-side copy — open your browser's network tab while you do it and watch: the file never appears.
Yes. OpenAnyFile's progressive image decoder runs in your browser, so you can read a EMF file with nothing installed. You get the picture drawn natively if your browser ships a decoder for this codec, and a full byte-level inspection with the detected signature if it does not. For full editing you still need the original application — this is a viewer, not an editor.
Look at the first bytes rather than the extension. A genuine EMF begins with 01 00 00 00. Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .emf by mistake is easy to spot.
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.

Yes — the same engine also opens .exr, .hdr, .jp2, so you can compare related files without switching tools.
These open with the same engine, so if you have one of these sitting next to your .emf file, it will open too:
