File Forensics
Reads a file’s bytes rather than its name: the type from its signature; the structure of PNG, JPEG, GIF, ZIP, PDF and RIFF files; Exif metadata with any GPS position, comments and text chunks; data after the point where the format ends; files embedded at any offset, ZIP entries unpacked; printable strings; and entropy along the file. The file never leaves the browser.
