Hex Editor - Binary File Editing Software for Windows

Bitwise Operations

Bitwise operations include NOT, OR, AND and XOR. The first operation does not require an operand, while all others require the operand of a given size. More information is provided in the table below (in the table below x is a variable containg currently processing value):

NameOperandOperation Description
NOTN/Ax = ~x
ORax = x | a
ANDax = x & a
XORax = x ^ a

The size of both operands depends on the view type of the current editor window.

Bitwise Operation Window

When you execute a bitwise operation, the following window appears:

Bitwise Operation Window

The operation you executed is automatically selected, but you can change it if you like.

If the chosen operation requires an operand, select its type and enter its value.

Using Patterns as Operands

You can use a pattern for a bitwise operation (except for NOT). In this case, the operation iterates through each byte (or word etc., depending on view type) as the operation is applied to the selection.


Non-byte size operands are always aligned.
