- Autofix: Hachoir is able to open invalid / truncated files
- Lazy: Open a file is very fast since no information is read from file, data are read and/or computed when the user ask for it
- Types: Hachoir has many predefined field types (integer, bit, string, etc.) and supports string with charset (ISO-8859-1, UTF-8, UTF-16, …)
- Addresses and sizes are stored in bit, so flags are stored as classic fields
- Endian: You have to set endian once, and then number are converted in the right endian
- Editor: Using Hachoir representation of data, you can edit, insert, remove data and then save in a new file.
