Application can be executed on any platform supported by Java 8, including Microsoft Windows, macOS, variants of Linux or BSD and application should have the same minimum requirements as Java. It should be also ok to use any newer version of the Java. DMG installer for macOS requires Java 11.

For instruction on how to install Java on your operating system please search on Internet or visit:



Application is available for download on the project's website:


To get the file scroll down to the Downloads section. Please use stable version if you want to have less problematic experience, as development version can contain unfinished/untested functionality.

For Windows there is currently only installer for x86 32-bit architecture available - after installation it can be used with either 32-bit or 64-bit Java.

For macOS there is installation file (dmg image) available.

For some Linux variants there are Debian and RPM packages available.

Alternatively, or for other operating systems, please use general ZIP variant / file. You'll need to extract content of the file into directory of your choice. This action is different on various operating systems - please search on the Internet for instructions on how to do this step on your operating system.

You can also run limited version in modern web browser using CheerpJ:


Installation on Windows

Installation package for Windows is typical wizard dialog (created with Nullsoft NSIS tool).

Installer - Step 1

It will also create shortcuts in start menu in ExBin Project folder.

Installer - Step 2

Specify in which directory you want to install the application or use default.

Installer - Step 3

Installation on macOS

Installation on macOS requires preexisting Java installation.

Download and open DMG file. Image should be mounted and installation process should start.

Installation - Step 1

To proceed with installation, agree to application license terms.

Installation - Step 2

Drag&Drop BinEd to Applications (from left to right) to perform installation.

Depending on the version of your system, you will encounter error when trying to execute the application.

Installation - Step 3

You'll need to add security exception in Mac System Settings / Privacy & Security as this application is not available via App Store.

Consult following page: MacHelp

Installation on Linux

Installation on Linux depends on the variant of the system. Some systems allow to perform the installation with simple execution of the downloaded file.

Alternatively you might need to use shell commands:

For Debian-based systems command might be:

sudo dpkg -i bined_*.deb

For RPM-based systems command might be:

sudo rpm -i bined-*.rpm

How to Use

To start the application directly, there are multiple options.

If you installed version for Windows via installer, you can start the application via Start menu in applications list.

Go to the directory where your application is installed.

You can start "bined.exe" on MS Windows systems or on systems with Windows emulation installed - for example using Wine.

"bined.sh" is a simple script which should work on Linux or macOS systems. It might be necessary to assign execution bit on the file (for example via "chmod +x bined.sh" command).

On some systems it might be also possible to execute "bined.jar" depending on how and which variant of the Java is installed.

Application can be also started via command line, but this might also depend on the operating system, Java version and whether are Java tool applications setup for direct execution.

java -jar bined.jar

Application also accepts few command line parameters, like for opening specific file on start.

Usage: "bined <options> <file>"

"--help" parameter to see available commands
"-multi_file" forces multi file / tab switching mode
"-single_file" forces single file mode
"--fullscreen" forces full screen mode

In basic mode, data are shown as matrix of numeric codes and also as regular text at the same time.

Optionally there is header, which represents position offset for the particular code on the given column.

Row starts optionally by row position. Row position can be represented by numbers in octal, decimal or hexadecimal base independent on code base.

Popup menu is available with actions which depends on which section of the code area was clicked on.

Parsing Panel

Content parsing panel provides analysis of the data at the cursor position.

Parsing panel can be shown/hidden with:

Menu / View / Show Parsing Panel

Currently, only simple list of values is available. Values are updated when cursor in code area is moved.

It's possible to edit the values and overwrite content of the document on the cursor position with ENTER key.

Values panel supports options for big and little endian - this affects order of bytes for multibyte values.Support for signed and unsigned variants of some values - first bit is typically used for negativity sign.

Status Bar

Status bar is bottom section of the main window.

Status Bar

It has following 5 sections - from left to right:

Current Encoding

Left click cycles throw set list of encodings.

Popup menu provides ability to select specific encoding from the list or to manage it.

Shows current position of the cursor in the document as position in the document and position in the code.

If there is selection active in the document then it shows start and end position of the selection.

Tooltip shows cursor position in three numeral systems of base 8, 10 and 16.

Popup menu allows selecting code type or to copy the value.

Memory Mode

Shows currently used memory mode.

Modes are:

Tooltip shows full name of the memory mode.

Popup menu allows switching memory mode. This will close the document and reopen it in selected mode.

Edit Mode

When done with editing operations, save file:

Menu / File / Save

Edit Mode

Two modes are supported:

In insert mode entering new codes or charaters inserts space at the current cursor position to insert new data. Inserting data from clipboard inserts this data at the current position (making additional space).

In overwrite mode data are replaced at the current cursor position. Inserting data from clipboards replaces data at the current position and only extends file if not enough space is available.

Text preview section is showing data decoded to textual characters according to currently selected encoding. Method of conversion between RAW data and characters is described in so called encoding. Java supports universal UNICODE encodings as well as various ISO and platform specific encodings often tailored for specific country/language.

Encodings can be either fixed where single numeric code is represented as single character. Some encodings like for example UTF-8 uses codes with different length of codes to represent characters. Each character in textual preview section is decoded from particular position, therefore characters longer than single byte will overlap.

User can set list of encodings available for quick switching in encodings manager dialog.

Manage Encodings Dialog
