About image cropping
Keep only the part of a JPG, PNG, or WebP image you need. Move the crop frame and resize it from any edge or corner while viewing the image.
How to use
- Add an image.
- Choose a ratio preset or custom crop size.
- Move and, outside Custom Size mode, resize the crop frame.
- Crop and download the result.
Aspect ratios
Free mode lets width and height change independently. Choose 1:1, 4:3, 3:2, 16:9, or Original Ratio to keep that ratio while resizing the frame.
Custom crop size
Specify the crop size in original-image pixels, then move the fixed-size crop area to choose what to keep. The selected pixels are exported without an additional resize.
Transparency
PNG and WebP transparency is preserved where possible. JPG cannot contain transparency and is rendered on a white background.
Your image is not uploaded
The image is decoded, cropped, and exported in your browser. nicolet.jp does not receive or store it.
