About this utility

How to use Binary Hex & File Signature Inspector

Inspect magic bytes, MIME hints, printable strings, entropy, and a bounded hexadecimal preview.

What to provide

Drop any file. Only a bounded prefix is read for inspection and the filename remains in this tab.

  1. Paste, type, or drag and drop a supported text file into the input area.
  2. Choose the options that match your intended result.
  3. Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.

What the result means

A signature report and bounded hexadecimal/ASCII rows.

Privacy and safety

This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.

Limitations

  • A signature match identifies a container family, not whether the complete file is valid or safe.
