Explore the internal structure of any file — a real structure tree, hex view, and field inspector, not just a wall of bytes.
If you're here because something threw one of these, this tool shows you exactly what's wrong and how much is recoverable:
There's no MP4/MOV, PE/ELF/Mach-O, disk-image, or game-console format support yet — those need real parsers this tool doesn't have. Structure, Hex, and the Field Inspector are separate views you switch between rather than three simultaneous panes, to keep the layout usable at every screen width. There's no click-and-drag byte selection — use the from-offset/length fields instead. Pointer fields aren't detected or made clickable, bit-level fields have no known semantic meaning attached (only the raw 8-bit breakdown), and structure trees for PDF and SQLite are shallow — top-level checks only, not a full object graph or b-tree walk. Nothing is persisted between visits: no bookmarks, no notes, no saved regions. Detected compressed streams (zlib/gzip headers) are flagged but never actually decompressed.
