Jak to funguje

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. 1
    You drop in any file
    The first 64 KB are read into memory locally — never uploaded.
  2. 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. 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. 4
    You inspect freely
    Scroll through the dump to find headers, signatures, or embedded strings.

Inspecting an unknown or suspicious file is exactly when you don't want to upload it. Everything is read on your device — nothing leaves the browser.
