Works
Viewing, inspecting and verifying. You get a playback bar with duration and seeking. File details, exact byte size and the detected signature are always shown.
You have a WAV 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.
Waveform Audio is an audio format developed by Microsoft / IBM, first appearing in 1991. It is normally produced by Recording studios, sound design.
Usually uncompressed PCM, so a CD-quality stereo minute is about 10 MB. The classic RIFF header caps files at 4 GB, roughly six hours of stereo.

OpenAnyFile routes .wav to its HTML5 audio player, which plays a playback bar with duration and seeking.

Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
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 .wav 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 HTML5 audio player runs in your browser, so you can read a WAV file with nothing installed. You get a playback bar with duration and seeking. 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 WAV begins with 52 49 46 46 .. 57 41 56 45. Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .wav 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 .mp3, .flac, .aac, 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 .wav file, it will open too:
