HxD

HxD is a robust and efficient hex editor built for users who need precise control over raw data. Whether you’re editing firmware, debugging a corrupted file, exploring memory, or reverse engineering, this tool gives you the flexibility and depth you need, all within a fast, user-friendly interface.

Designed to handle demanding binary editing tasks, HxD strikes a balance between power and simplicity, making it ideal for both seasoned professionals and newcomers.

Smart Hex Editing Made Accessible

Hexadecimal data isn’t naturally readable, and making sense of it can be a challenge. HxD simplifies this with a clean interface that displays hexadecimal values alongside their ASCII equivalents. What makes it even more user-friendly is how it highlights any changes you make in red, helping you instantly identify edits.

Standard editing features like cut, copy, paste, and undo are available, as is the ability to define block ranges, split and merge files, and compare contents of different files.

These tools help streamline complex workflows and give users the control needed for precise modifications.

Designed for Performance

HxD excels in managing very large files, such as multi-gigabyte logs or disk images. Instead of loading everything into memory, it reads only the necessary sections, which ensures smooth and fast performance even on systems with modest hardware.

Despite its power, the application remains lightweight. It runs with minimal impact on your system, allowing you to perform detailed editing tasks without disrupting other active programs.

Full Access to Disks and Memory

Beyond standard file editing, HxD enables users to open and modify raw disk sectors and the main memory of running processes. This capability is invaluable for tasks like analyzing malware, repairing boot records, or inspecting system memory contents.

It also includes a detailed search feature with filter options and support for pattern matching, making it easy to locate specific byte sequences or phrases quickly. Exporting edited content is straightforward, with support for multiple formats such as Java, C++, HTML, and 16-bit code.
