Received a file with an unknown extension or need to validate uploads on your server? This tool reads the file’s binary signature (magic number) to determine its true MIME type (e.g., image/jpeg, application/pdf), independent of its filename. It also displays the exact file size, original name, and last modification timestamp. Crucial for developers building secure file upload features and system administrators auditing file integrity. Check any file safely and privately.
