How it works
Analyze the technical properties of any file directly in your browser.
Upload a file to get information such as the exact MIME type, file size, and last modification date. For experts, even the hex header (the first 32 bytes) is displayed to identify the true file type regardless of the file extension.
Processing happens entirely locally in your browser.
