OpenAnyFile
You have a XPS 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.
XML Paper Specification is an archive format developed by Microsoft, first appearing in 2006. It is normally produced by Microsoft XPS Document Writer.
Microsoft's fixed-layout answer to PDF. A ZIP of XML pages; it never gained traction and Windows dropped the built-in viewer.

OpenAnyFile routes .xps to its ZIP archive browser, which opens a clickable folder tree — walk into directories and open any file inside without extracting, including archives nested in archives.
Viewing, inspecting and verifying. You get a clickable folder tree — walk into directories and open any file inside without extracting, including archives nested in archives. File details, exact byte size and the detected signature are always shown.
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 .xps 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 ZIP archive browser runs in your browser, so you can read a XPS file with nothing installed. You get a clickable folder tree — walk into directories and open any file inside without extracting, including archives nested in archives. 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 XPS begins with 50 4B 03 04 (PK..). Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .xps 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 .epub, .zip, .apk, 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 .xps file, it will open too:
