Img4Helper is a small tool built for handling Apple’s Image4 format used for the boot files in iOS/iPadOS and other operating systems built by Apple. It’s purpose is to make analysis, decryption, decompression and extracting these files easier. Img4Helper (and Libhelper) are open-source, so please check it out of Github where I have a more in-depth discussion of the tool.
Special thanks to @tihmstar and @xerub. Although they did not personally help me with this project, by open-sourcing both img4tool and sepsplit they made this possible.
Changelog
This is the first non-Beta Release of Img4helper. Thank you for using Img4helper, please Tweet me @h3adsh0tzz with what you think and/or if you have any issues. You can checkout the usage documentation on Img4helper’s Github.

Experimental Builds of Img4helper are available for macOS on both Intel x86_64 and Apple Silicon AArch64 architectures. There should not be any compatibility issues between them, but please report any issue you encounter - whether they may be architecture related or not.
As always, Img4helper is available on Github fully open-sourced, and you are welcome to contribute, Here are a few features I still plan to add at some point:
- Create an
.img4
from a combination of.im4p
,.im4m
or.im4r
. - Improving the way Img4helper decrypts files, e.g. adding an option to specify KEY and IV seperately.
