Files & media Local only
Binary File & Hex Inspector
Local byte analysisInspect bytes, signatures, parsed structures, strings, entropy, hashes, searches, and binary differences.
Inspect any file as bytes
Use a hex view, magic signatures, bounded structure parsers, strings, entropy, cryptographic hashes, wildcard search and binary comparison without executing the file.
Files remain inert and local
The browser reads bytes only. It does not execute binaries or upload data; files larger than 32 MiB use a clearly labeled leading sample.
How to use it
- 01
Load bounded bytes
Open any file locally; files up to 32 MiB are analyzed exactly and larger accepted files use a clearly labeled leading sample.
- 02
Inspect structure and evidence
Navigate offsets, interpret scalar values, detect magic signatures, parse supported structures, extract strings and profile entropy.
- 03
Search, compare and export
Search hex with wildcards or text encodings, compare a second file, and export privacy-safe JSON or Markdown evidence.
Frequently asked questions
Which formats have structural parsers?
The current bounded parsers cover PNG, JPEG, GIF, WebP, ZIP, PDF, WebAssembly, PE, ELF and Mach-O. Unknown formats still receive hex, strings, entropy, hashes and search tools.
Are large files fully hashed?
Only when all bytes are loaded. Accepted files above 32 MiB use a leading sample and every derived hash and finding is labeled as sample-scoped.
Does high entropy mean malware or encryption?
No. Compression, encryption and naturally dense media can all raise entropy. It is a navigation clue, not a verdict.
Does opening an executable run it?
No. Files are read as inert bytes. The editor does not execute, emulate, decompress arbitrary payloads, or invoke operating-system handlers.
