Common Questions (Q&A):

1. Q: Does cropping reduce image quality?
   A: Cropping only removes outer areas and does not downscale the kept region. JPEG or WebP export quality settings may still affect output clarity.
2. Q: Are images uploaded to a server?
   A: No. Images are read and cropped locally in the browser, which is useful for private photos, product assets, and unpublished materials.
3. Q: How do I batch crop to one aspect ratio?
   A: Upload multiple images, choose a ratio such as 1:1, 16:9, or custom W:H, then run the batch crop.
