hexJapality

HexJapality is a mobile hex editor and binary analysis toolbox for developers, students, and technical users who need to inspect files at the byte level.

Open local files, move through offsets, and view bytes in HEX, DEC, OCT, or BIN with printable ASCII alongside the raw data. Select any byte to inspect common interpretations including unsigned integers, signed integers, floats, binary, hex, and ASCII.

Built-in tools help you understand file structure faster:

Edit individual bytes with undo and redo before saving

Search for text or exact hex byte patterns

View file size, MD5, and SHA-256

Detect common formats such as PNG, JPEG, PDF, ZIP, ELF, and GIF

Explore entropy and byte distribution maps

Scan for readable strings and jump to offsets

Add bookmarks for important locations

Compare two files with Binary Diff

Export bytes as a C array, Rust array, hex string, or Base64

HexJapality is designed for quick checks and byte-level inspection on mobile.
