Works
Viewing, inspecting and verifying. You get an interactive model you can orbit, pan and zoom, with lighting and a ground plane. File details, exact byte size and the detected signature are always shown.
Opening a BLEND file usually means tracking down Blender. It does not have to. Here is what the format really is, and a browser-based way to read one right now.
Blender Project is a 3d & cad format developed by Blender Foundation, first appearing in 1994. It is normally produced by Blender.
Essentially a memory dump of Blender's internal structures plus a schema (DNA block) describing them, which is how old .blend files still open in new releases.

OpenAnyFile routes .blend to its WebGL 3D stage, which loads an interactive model you can orbit, pan and zoom, with lighting and a ground plane.

Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need Blender 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 .blend 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 WebGL 3D stage runs in your browser, so you can read a BLEND file with nothing installed. You get an interactive model you can orbit, pan and zoom, with lighting and a ground plane. 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 BLEND begins with 42 4C 45 4E 44 45 52 (BLENDER). Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .blend 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 .dwg, .dxf, .fbx, 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 .blend file, it will open too:
