Works
Viewing, inspecting and verifying. You get a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis. File details, exact byte size and the detected signature are always shown.
You have a XCF 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.
eXperimental Computing Facility is a binary & system format developed by GIMP team, first appearing in 1995. It is normally produced by GIMP.
GIMP's native layered format, named after the Berkeley lab where GIMP was written. Deliberately not standardised — the format changes between GIMP releases.

OpenAnyFile routes .xcf to its universal hex inspector, which inspects a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis.

Full-fidelity rendering. This extension has no standard structure, so you get a byte-level inspection rather than a rendered view.
Plenty of sites promise they delete your uploads. OpenAnyFile avoids the promise by avoiding the upload. When you drop a .xcf 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 universal hex inspector runs in your browser, so you can read a XCF file with nothing installed. You get a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis. It will not replace the original application for editing, but it answers 'what is in this file' in seconds.
Look at the first bytes rather than the extension. A genuine XCF begins with 67 69 6D 70 20 78 63 66 (gimp xcf). Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .xcf 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 .dll, .doc, .exe, 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 .xcf file, it will open too:
