Open Image CropperFrequently Asked Questions
What aspect ratio should I use when cropping an image?
Choose an aspect ratio based on where the image will be used. Common options include 1:1 for square profile avatars, 4:5 for vertical social posts, 9:16 for Stories and Reels, 16:9 for landscape banners, and 4:3 or 3:2 for standard photo framing.
Can I crop an image without changing its aspect ratio?
Yes. Use the cropper's freeform mode or select an appropriate aspect-ratio preset depending on whether you want unrestricted cropping or fixed proportions.
Does cropping reduce image quality?
Cropping removes part of the original image. The remaining area retains its original visual quality, although the final output pixel resolution depends on the cropped dimensions and output format settings.

Yes. The crop box supports touch dragging on mobile devices as well as quick directional nudge buttons for precise positioning.
