## Tips

- Crop a reference image to the shape you'll generate in, so the AI doesn't have to stretch or pad it.
- In Midjourney, the --ar flag sets the shape of the new image, like --ar 9:16.
- Put the subject on one of the grid's third lines for a balanced frame.
- Cropping can't add pixels. For a large print, start from the biggest version of the image.

## FAQ

### Is my image uploaded?

No. It's cropped on your device and never leaves it.

### Which shapes can I crop to?

1:1, 16:9, 9:16, 4:5, 3:2, 2:3, 4:3 and 21:9, or any shape with Free.

### Does cropping lower the quality?

The cropped part keeps its original pixels. PNG and WebP files stay in their format; other images are saved as high-quality JPG.

### Which shape should I use?

Match where the image ends up: 1:1 for square posts, 4:5 for the Instagram feed, 9:16 for Reels, TikTok and Shorts, and 16:9 for YouTube and slides.
