Image cropper
Remove the edges you do not need. Choose a JPEG, PNG, or WebP, define the crop in source pixels, and save a new PNG without uploading the original.
Image cropper
Runs on your deviceCropping changes the composition
Resizing changes the number of pixels across the whole image. Cropping keeps only a selected rectangle. A crop can remove empty margins, focus on a subject, or fit a document’s layout. This tool uses pixel coordinates measured from the source image’s top-left corner: left increases to the right, and top increases downward. Width and height must fit within the remaining source area.
Review what the crop removes
The shaded preview shows the portion that will be kept. A crop is a new composition, and important context can be lost at an edge. Inspect faces, labels, signatures, and the surroundings before sharing. The exported image uses the exact selected source dimensions rather than stretching the crop into another shape. To reduce those dimensions afterward, use the separate image resizer.
Keep an untouched original
The output is a new PNG file. It preserves transparent pixels in the selected area and may be larger than a JPEG source because PNG uses a different encoding. This browser redraws the crop rather than intentionally copying the original metadata. Animated input becomes a still image. The tool accepts at most 24 million source pixels and 16 million crop pixels; keep the original if you may need another framing later.
Worked examples
| Source | Crop rectangle | Output |
|---|---|---|
| 1600 × 800 px | Left 400, top 100, width 600, height 400 | 600 × 400 px |
| 800 × 800 px | Left 0, top 0, width 400, height 400 | Top-left quarter |
Good questions.
Does cropping stretch the picture?
No. It copies the selected rectangle at its original pixel dimensions.
Can I undo it after downloading?
The original file is not changed. Return to that original to make a different crop.
Why is the PNG larger than the original photo?
PNG and JPEG store images differently. The crop may have fewer pixels yet use more bytes.
