Hex Editor Neo Advanced Features

Neo is a Freemium Hex Editor which means that it provides you with absolutely free basic editing features, while some advanced features require payment.

Here's a list of advanced features.

Base converter

The base calculator automatically converts data between the hexadecimal, decimal/integer, octal, float, double, ASCII, EBCDIC and UNICODE.

130+ Different Encodings

Hex Editor supports displaying text in more than 130 different character encodings including ANSI, EBCDIC, UNICODE, ISO, OEM, ISCII, MAC, US-ASCII (7-bit), KOI8-R, KOI8-U, T.61, EUC, IA5, Europa 3, IBM5550, Asian and more. Multi-byte UNICODE character sets are also supported including UTF-8 and UTF-16.

Byte editor (Bits editing)

An easy-to-use visual tool that allows modification of individual bits for hex, decimal/integer and octal data, create bit masks and edit it in a convenient way.

Disk editor/Drive Editor/Sector Editor

Hex Editor Neo provides advanced disk editing features, allowing you to read/edit disk sectors and write raw data to physical disks drives (including volumes, partitions and files). Product parses partition tables and disk volumes, analyzes file system (NTFS/FAT/FAT32/ExFAT) and displays disk structure: folders, files and streams. It supports hard disk drives (HDD) and solid state drives (SSD) disk editing.

Windows Virtual Memory Editor

It provides you with an easy way open virtual address space and edit virtual memory blocks of any Windows process.

Data encryption and decryption

Neo Editor allows you to encrypt or decrypt file or its part using the following algorithms: RSA Security RC2 (ARC2) or RC4 (Rivest Cipher 4 aka ARC4), Data Encryption Standard (DES) symmetric-key algorithm, two-key/three-key Triple DES encryption (3DES or TDES), Advanced Encryption Standard 128-bit, AES 192 bits, AES 256 bits.

Logical bitwise and arithmetic operations

HexEditor supports Bitwise operators: NOT, OR, AND, XOR, Arithmetic operators: Negation, Addition, Subtraction, Multiplication, Division, Remainder, Logical and Arithmetic Shifts, Reverse Bits, Byte Swap.

Editing Intel HEX files (Intel Hex files viewer/editor)

Hex Editor Neo allows you to open and edit Intel HEX files. It supports editing Intel HEX files of the following formats: Intel HEX 8-bit (I8HEX), Intel HEX 16-bit (I16HEX), Intel HEX 32-bit (I32HEX).

Editing Motorola S-record files (Motorola s-record viewer/editor)

Hex Editor Neo allows you to open and edit Motorola S-record files. It supports editing Motorola Srecord files of the following formats: Motorola S19 (SREC S19), Motorola S28 (SREC S28), Motorola S37 (SREC S37).

Hash/Checksum Calculator

Hex Editor Neo supports 20+ of the most common checksum calculation algorithms. It supports hash calculation algorithms: Message-Digest - MD2, MD4, MD5, Secure Hash - SHA-1, SHA-256, SHA-384, SHA-512, RIPEMD Message Digest - RIPEMD-128, RIPEMD-160, FNV-1/FNV-1a hash and the following checksum calculation algorithms: CRC-16, CCITT CRC16, CRC-32, CRC XMODEM, CRC-64, CRC-64/WE, CRC-64/XZ, Adler-32, Fletcher-32.

Search in files/replace in files

Hex Editor Neo allows you to find(replace) specified binary data among files within disks or folders. You can search/replace in folders using RegExp patterns. Searching in NTFS streams is also supported.

NTFS streams viewer/editor

Product allows you to easily view and edit NTFS alternate data streams.

Compare files (binary diff/hex diff tool)

Neo Hex Editor provides you with powerful binary and hex diff tool for Windows allowing you to compare several binary files using two different algorithms: simple binary comparison and advanced block matching algorithm that allows you to isolate differences between binary files or hex dumps. Both perform well on large files.

Hex Editor Binary Templates (Structure Viewer)

Hex Editor Neo provides you with advanced binary data analysis and editing function called Structure Viewer. This feature allows you to bind binary templates to the data, allowing you to easily edit binary files and dumps according to the appropriate data format. For many known file types hex editor automatically loads built-in binary template from the library and parses data in the Structure View tool window. It supports Kaitai struct definitions.

Disassembler

Hex Editor Neo allows you to disassemble x86, x64 and .NET executable files. It supports x86, x86-64, MMX, SSE, SSE2, 3DNow!, MSIL instruction sets. You can load symbol files for both 32-bit and 64-bit executables. Neo is a perfect dll/exe files editor!

Hex Editor Neo disassembler also supports ARM, ARM-64 (ARMv8/AArch64), Cortex-A, MIPS, RISC-V (and other RISC microprocessor architectures), PowerPC, SPARC, XCore, Motorola 68K, 680X, MOS65XX (including 6502), Texas Instruments TMS320C64X, IBM System z architectures and more.

Hex Editor Neo also offer Bookmarks, Data analysis and statistics, SDK, Scripting, Macros recording and even more useful functions for you. Download it now!
