The short version: PKPASS is an Apple Wallet Pass from Apple. The longer version — including the quirk that trips most people up — is below, along with a viewer that runs entirely on your own device.
Apple Wallet Pass is an archive format developed by Apple, first appearing in 2012. It is normally produced by Airlines, event ticketing.
A signed ZIP containing pass.json plus images. The signature is what stops anyone editing a boarding pass's seat number.

OpenAnyFile routes .pkpass 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.
The entire pipeline — detection, decoding, rendering — runs client-side. Your browser hands the bytes to a decoder compiled to WebAssembly, the result is drawn to the page, and that is the whole journey. No account is created, no file is stored, and no analytics event carries your filename. This is also why there is no size limit imposed by a server: the only ceiling is your own available memory.
Yes. OpenAnyFile's ZIP archive browser runs in your browser, so you can read a PKPASS 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 PKPASS 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 .pkpass 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 .pkpass file, it will open too:
