Hex Dump Viewer

Inspect files and text as a hex dump in your browser

A hex dump prints raw bytes as hexadecimal values beside an ASCII column. Forensics engineers, game modders, and API developers use dumps to verify magic bytes, spot null padding, and compare binary payloads without installing a desktop hex editor. This viewer reads up to 10 MB locally, nothing is uploaded.

How to use the hex dump viewer

1. Drop a file or paste text to load bytes into memory.
2. Pick 8, 16, or 32 bytes per row to match your preferred dump layout.
3. Click any byte to see decimal, hex, binary, and ASCII interpretations.
4. Search by hex pattern (for example 89 50 4E 47 for PNG), ASCII text, or a single decimal value.
