Purpose: Q22 is a cross-platform binary file editor and the successor to Catch22 HexEdit for Windows.
Editing: It can open and edit binary files, including large files, with cut, copy, paste, insert, delete, undo and redo.
Data views: It displays data as hexadecimal, decimal, octal, binary or text, and groups bytes as 8-bit, 16-bit, 32-bit or 64-bit values.
Structure View: Structure View supports PE and ELF files, can expand their headers, sections, imports, exports and symbols, and accepts custom .strata definitions in Strata.
Disassembly: The disassembler supports x86 64-bit, x86 32-bit, ARM, ARM Thumb and AArch64, and detects PE and ELF entrypoints automatically.
Bookmarks: Users can bookmark and highlight positions in the hex display, and bookmark state is saved for future use.
Import and export: Supported clipboard, import and export formats include hex, ASCII/text, raw data, Base64, UUEncode, Intel HEX, Motorola S-records, HTML, C++, C and assembler-style data.
Other tools: The interface includes file properties, checksum calculation and string extraction panels.
Customization: Q22 offers light, dark and system themes, built-in and custom palettes, configurable preferences, a custom titlebar and docked panels.
Window integration: Its platform-specific window chrome supports Windows, KDE/KWin and GNOME/Mutter.
Platforms: The page lists Linux (Fedora currently) and Windows as supported platforms and says more are to come.
License: Q22 is licensed under GPL-3.0-or-later.
