Free Hex Editor Neo Features

  • Opening and efficient handling of huge files
    Opening and efficient handling of huge files

    During hex editor program development we focused on its performance and reliability, so the product is based on the most advanced and efficient data processing algorithms. We have created an absolutely unique data editing software, which is able to successfully handle files of ANY size and has absolutely no analogues in this regard. Thus, any extra large file supported by the underlying file system (FAT, FAT32, NTFS) is automatically supported by our product.

  • Instant data processing regardless of size
    Instant data processing regardless of size

    Thanks to the use of highly efficient algorithms, hardware acceleration and extensive use of multi-threading technology, the product always remains responsive and quickly performs all binary data editing and file modification operations (including basic I/O, search, replace and clipboard operations) with data blocks of unlimited size. Thus, only using our hex editing software you avoid situations when you lose all modifications due to unpredictably long data processing operations.

  • Basic file editing features
    Basic file editing features

    Using this binary file editing software, you can perform most manipulations with the file data. You can type data, write data to file (direct hex file modification), select data, remove selections, insert data into file, delete binary data from file, insert another file, fill selection with raw hex data patterns, save/load files. It supports overwrite/insert writing modes and allows you to use clipboard: cut, copy/paste, merge data. Modified data is highlighted. You can use 'goto offset' command or make quick address bookmarks for easy navigation.

  • Editing files opened in external applications
    Editing files opened in external applications

    Our hexadecimal editor may share edited binary files with external applications. When an external application modifies a shared file, HexEdit Neo detects it and allows you to either discard the changes or merge it with modifications already made in the editor. Automatic file compare utility (hex diff tool) may be used to find differences between the current and previous versions. Optionally, all previous revisions of the file may be kept by the hex editor app and used in your work.

  • Advanced formatting & grouping options
    Advanced formatting & grouping options

    By default Hex Editor Neo displays binary/hexadecimal data as a grid of cells with editable hex codes and allows you to configure number of columns. Codes can be displayed as Binary, Hex, Decimal, Octal, Float or Double grouped by Bytes, Words, Double Words and Quad Words allowing you to view and edit it in a variety of formats, including single-precision floating-point format (IEEE 754) and double-precision floating-point format (IEEE 754). A view type is a property of individual editor window, so you can open several editor windows with different view types for your convenience.

Input fields store entered values and provide you with a list of recently used items.

  • Instant search for specific data
    Instant search for specific data

    The Find command allows you to search data within selection or whole file and instantly find Binary/Hex data patterns. Searching for Decimal/Octal/Float/Double patterns is also supported. Product supports searching for chars and ASCII text strings as well as Unicode texts. When the pattern is found, the cursor is moved to the beginning of located fragment. To continue searching, just use the 'Edit » Find Next' or 'Edit » Find Previous' commands. In order to find binary-values, hex-values, byte patterns, integers, floats or texts just switch input type, then your choice and search history will be saved for your convenience.

  • Instant search with data replacement
    Instant search with data replacement

    The Replace command is used to find a specific hex/text pattern in a binary file and replace it with different one. The Find & Replace Dialog is used to specify both patterns and search options. The length of the search and replace pattern is not limited and you can replace any found fragment with a different fragment of arbitrary length or even with an empty one (the found pattern occurrences are removed from the document). When you use replacing function, binary file editor starts searching for a pattern. When pattern is located, the cursor is moved to the beginning of the pattern and a number of options are provided.

  • Unlimited Undo and Redo
    Unlimited Undo and Redo
