Frequently asked questions
- Can I crop an image into a circle?
- Yes. Select the circle shape crop mode, position your selection, and export as PNG to preserve transparency. The circular crop creates a transparent background around the subject.
- How do I crop to an exact pixel size?
- Enter your target width and height in pixels, then drag the crop region to select which part of the image to keep. The selection will maintain your exact dimensions.
- Does cropping reduce image quality?
- Cropping does not recompress or degrade the image. The cropped area is extracted at the original quality. Only the portion outside the crop is removed.
