Identify a file type free
Looks at the first bytes of a file to see what it really is, whatever its name says.
When do you use this?
Handy when a file has a strange extension or you do not trust a download.
Good to know
Tested with a ZIP file that I named 'foto.jpg': the tool recognised ZIP archive (application/zip), showed the first bytes and warned about the wrong extension. You can have several files checked at once. English interface. The site measures visits with Microsoft Clarity.
On this tool’s website: Microsoft Clarity (analytics) seen; no ads seen.
