9Grid: Grid Post & Image Split

This app makes it easy to split images for Instagram grid posts.
All features are completely free to use, with no registration or login required.

In addition to image splitting, it also supports basic editing such as cropping, resizing, and rotation/flip.
You can also convert images to JPEG, PNG, HEIC, or WebP, compress images, and remove EXIF information.

By subscribing to the paid plan, you can remove ads and unlock batch processing.
Even in batch mode, you can fine-tune each image individually, making processing more efficient.
A 1-month free trial is currently available, so give it a try!
