사용 방법
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.
- 1You drop in any fileThe first 64 KB are read into memory locally — never uploaded.
- 2The bytes are laid outEach row shows the offset, 16 bytes in hexadecimal, and their printable ASCII representation, just like a desktop hex editor.
- 3The type is detectedThe leading bytes are checked against common magic-number signatures (PNG, PDF, ZIP, MP4, ELF, and more) to identify the real file type.
- 4You inspect freelyScroll 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.
