What is this file?

Drop any file and we identify it by its actual bytes — not the name, which can lie. You get what it is, how to open it, and a one-click jump into the right diagnostics tool when we have one. Nothing is uploaded.

Drop any file — we'll tell you what it really is

Identified by magic bytes, not the file name, so renamed and extension-less files don't fool it. Files never leave your browser.
