Image Cropper

live

This lightweight cropper exports the largest centered crop for the selected ratio, with rotation and flip applied locally.

Good times to use it

Use Image Cropper for preparing product photos, thumbnails, avatars, social images, and page artwork that must fit a fixed frame. It works well when you want a cropped image exported in the selected format and quality and do not need a bigger workflow around it.

  • Best fit: preparing product photos, thumbnails, avatars, social images, and page artwork that must fit a fixed frame.
  • You start with one image with enough surrounding area to crop safely.
  • The useful choices are aspect ratio, rotation, flip direction, output format, and quality.
  • Check subject placement, edge cutoffs, text readability, and whether the crop matches the destination frame.
  • You end up with a cropped image exported in the selected format and quality.

Use Image Cropper like this

  1. Start with one image with enough surrounding area to crop safely.
  2. Choose aspect ratio, rotation, flip direction, output format, and quality.
  3. Run the tool once, then review subject placement, edge cutoffs, text readability, and whether the crop matches the destination frame.
  4. Copy, export, or download a cropped image exported in the selected format and quality.
  5. Open the export at the size people will actually see before you publish it.

Easy ways to ruin the result

  • Canvas export re-encodes the image, so output quality and file size depend on the selected format and quality setting.
  • Cropping before resizing usually preserves composition better than resizing first and then forcing a crop.
  • Use square crops for avatars and catalog grids, and 16:9 crops for headers, videos, and preview cards.
  • Keep important text and faces away from the edges because many platforms add their own rounded corners or overlays.

What changes the output

  • The selected image is loaded into browser memory and drawn to a canvas.
  • The crop preview uses the largest centered crop for the selected aspect ratio, with rotation and flip applied locally.
  • The canvas export creates the downloadable output file in the selected format and quality.
