hexJapality

Inspect, edit, compare, and export file data with a hex grid, data inspector, entropy chart, byte map, strings, hashes, and binary diff.

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.
