Como funciona

Sometimes you need to see what's really inside a file — its header bytes, a magic number, or some embedded text. This shows a classic hex dump, all in your browser.

1
You drop in any file
The first 64 KB are read into memory locally — never uploaded.
2
The bytes are laid out
Each row shows the offset, 16 bytes in hexadecimal, and their printable ASCII representation, just like a desktop hex editor.
3
The type is detected
The leading bytes are checked against common magic-number signatures (PNG, PDF, ZIP, MP4, ELF, and more) to identify the real file type.
4
You inspect freely
Scroll through the dump to find headers, signatures, or embedded strings.
