About HexEd.it
HexEd.it displays binary/hexadecimal data as a grid of cells with editable hex codes.
A text representation is shown aside of the hex codes, and supports more than 50 different encodings, including EBCDIC, IBM437, IBM866, ISO-8859-1 to -16, KOI8-R/-U and many more.
Here, you can enter data, select data, remove selections, insert data into files, delete binary data from files, save/load files. Modified data is highlighted.
HexEd.it can process files up to several terabytes. Your files are not kept in memory. This means that the displayed data is read directly from your hard drive. It also means there is no delay in opening and editing large files.
Using highly efficient algorithms, you can also create new files in memory up to 10 GiB in size, even if you don’t have that much RAM.
Data can be interpreted in different formats like 8/16/24/32/64 signed and unsigned integers, 16/32/64 bit floating-point numbers (IEEE 754), but also in LEB128 format and numerous Date/Time formats. And all this in Little Endian (Intel format) and Big Endian (Motorola format). Additionally, bit-wise editing is also possible.
HexEd.it decodes and encodes your Motorola S-Record and Intel HEX files. Including full editing support and the possibility to adjust the ranges which are stored in the file.
Export data in formats, which allow you to directly use them in other software or programming languages.
Supported formats are CSV, Plain data, C, JavaScript (ES6), Python, Rust and TypeScript.
HexEd.it offers the possibility to calculate statistical information based on your data. In addition to descriptive statistics (mean, median, sample variance, standard deviation, minimum, maximum, average value), an entropy analysis can also be performed.
In a histogram, the distribution of bytes/characters, either for the entire file or for individual areas, is graphically displayed. Multiple selections are also supported here.
HexEd.it has a built-in file hash generator, which supports BLAKE2b, BLAKE2s, CRC32, MD4, MD5, RIPEMD-160, SHA-1, SHA-2 (SHA-224, SHA-256, SHA-384, SHA-512), SHA-3 (SHA3-224, SHA3-256, SHA3-384, SHA3-512), Keccak (Keccak-224, Keccak-256, Keccak-384, Keccak-512), xxHash (xxHash32, xxHash64) and HMAC (with all these algorithms).
HexEd.it is completely multilingual. It’s translated into more than 40 languages, including right-to-left languages.
An included translation tool enables everyone to translate the UI into any language.
