The Crop tool sits in the left toolbox.
Steps
- Open a photo or video in the editor → click Crop in the tools column.
- Pick an aspect ratio preset (1:1, 4:5, 16:9, 9:16, 3:4) or Freeform to drag corners.
- For video: freeform crop honors even-dimension libx264 requirements (crop math auto-rounds).
- Straighten slider fine-tunes rotation ±15°.
- Click Apply to bake the crop.
Auto-fit per platform
Instead of manually cropping per platform, tick multiple targets in the composer — kuhukoo warns when the source aspect doesn't fit and offers auto-crop for supported platforms.
