Okteta

What Okteta is

Okteta is a Linux hex editor for viewing and editing the raw data in files. It displays byte values and characters in columns or rows, with each value above its character in row view. Editing and navigation resemble a text editor, and undo and redo are supported. Users can keep multiple files open and customize data views, saving profiles to load later. Numerical displays include hexadecimal, decimal, octal, and binary; character encodings include Qt's 8-bit encodings and EBCDIC. The Structures tool analyzes and edits data using definitions users create. Tools can be docked at any side of the window or shown as floating windows. The application lists fast on-screen rendering as a feature. Okteta is free and open source under GPL-2.0 and GPL-3.0. Linux installation is available through AppStream stores, distribution package managers, and Flathub. The project also says developers can reuse its Qt-based libraries in their code. The KDE page links to the Okteta Handbook, KDE forum, and bug-report page for help.
