Common questions

Does cropping reduce image quality?

Cropping only removes outer areas and does not downscale the kept region. JPEG or WebP export quality settings may still affect output clarity.

Are images uploaded to a server?

No. Images are read and cropped locally in the browser, which is useful for private photos, product assets, and unpublished materials.

How do I batch crop to one aspect ratio?

Upload multiple images, choose a ratio such as 1:1, 16:9, or custom W:H, then run the batch crop.
