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.
The short version: APE is a Monkey's Audio from Matthew T. Ashland. The longer version — including the quirk that trips most people up — is below, along with a viewer that runs entirely on your own device.
Monkey's Audio is an audio format developed by Matthew T. Ashland, first appearing in 2000. It is normally produced by Lossless CD archiving communities.
Compresses tighter than FLAC, but decoding is asymmetric and CPU-heavy, which is why hardware players and phones almost never support it.

OpenAnyFile routes .ape 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.
Plenty of sites promise they delete your uploads. OpenAnyFile avoids the promise by avoiding the upload. When you drop a .ape file in, the browser grants the page temporary read access to those bytes and nothing more — the page has no path to send them anywhere. You can verify it in seconds: open DevTools, switch to the network tab, and open a file. The request list stays empty.
Yes. OpenAnyFile's HTML5 audio player runs in your browser, so you can read a APE 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 APE begins with 4D 41 43 20 (MAC ). Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .ape 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, .wav, 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 .ape file, it will open too:
