OpenAnyFile
If double-clicking a IPA file did nothing useful, that is normal: the format is fine, your operating system just has no default application registered for it. This page explains the format and gives you a way to read one immediately.
iOS App Archive is an archive format developed by Apple, first appearing in 2008. It is normally produced by Xcode, App Store.
A ZIP with a Payload/ folder holding the .app bundle. App Store copies are FairPlay-encrypted and will not run when sideloaded.

OpenAnyFile routes .ipa 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.
It depends entirely on whether the website uploads it, and almost all of them do. That is a real problem when the archives file in question is a contract, a client deliverable or something under NDA. OpenAnyFile removes the question: the decoding happens inside your browser tab, so there is no transfer, no queue, no temporary storage and no retention window to read about in a privacy policy.
Yes. OpenAnyFile's ZIP archive browser runs in your browser, so you can read a IPA 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 IPA 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 .ipa 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 .ipa file, it will open too:
