— About Image Handling —
All processing is done entirely on your device.
Your content is never uploaded or shared.
・ Added an image size limit option to the pre-crop feature
・ Fixed an issue where images could not be saved in WebP format
You can now set a maximum image size based on the longest side of the image when pre-cropping.
Example: Image size limit set to 1280 px
4032 × 3024 → 1280 × 960
This is useful when you want to intentionally reduce the image resolution for samples or fine-tune the image size to meet the requirements of different publishing platforms.
