About Image Cropper

Crop an image by dragging a rectangle over it and cutting exactly what you framed. Nothing is computed from a guess at coordinates: you see the picture, you draw the box, and the output is the pixels inside it — the way cropping should work when composition matters.

Fixing the framing of a photo — taking out the clutter, keeping the subject.

How to use Image Cropper in 3 steps

  1. Drop one image onto the drop area and it appears as a preview.
  2. Drag a rectangle over the part you want to keep.
  3. Apply Crop and download the trimmed image.

Image Cropper: questions

Why can I only crop one image at a time?
The rectangle is drawn on a single preview, which is what makes it accurate. For a batch at a fixed ratio, use Resize by Aspect Ratio, which fits or fills every image to the same shape.
Does cropping reduce quality?
No. It removes area and keeps the remaining pixels as they are. You lose the option to show what was outside the box, so keep the original if framing might change later.
Can I crop to a circle for an avatar?
Crop to a square here, then use Round Image Corners to make the corners circular and save as PNG with alpha.
