Image Cropper

How the crop box is measured

X and Y are the distance in pixels from the left edge and the top edge to the corner of the box. Width and height are its size. The box must lie completely inside the picture. If it does not, the request is refused with "The crop area falls outside the bounds of the image" instead of being trimmed to fit, and a width or height of 0 is refused too. Dragging on the preview and typing numbers change the same four values, so you can drag roughly and then fine-tune the numbers.

Phone photos and the rotation flag

Many phone photos are stored sideways with a flag that tells viewers how to turn them. This tool applies that flag to the pixels before cropping, so X and Y refer to the picture as you see it. In our test, a photo stored at 600 × 400 with a "turn clockwise" flag was treated as 400 × 600, and a 100 × 100 crop at X 0, Y 0 took its upright top-left corner. The result has no rotation flag any more and no other camera data.

Does cropping lose quality?

The kept pixels are not copied bit for bit in every format, so it depends on the format:

Generated locally; not a benchmark; not a guaranteed result. A single crop is not visible to the eye, but each further save of a JPG or WebP adds a little. If you need several edits, do the crop last, or work from the original each time.

Crop, resize or both

Crop removes parts of the frame and keeps the pixels that remain at their original size, so a cropped file is smaller because it has fewer pixels, not because anything was compressed. To change the scale of the whole picture, use the Image Resizer. A common order is to crop first to the framing you want, then resize the cropped result to the size the destination needs. To straighten a sideways picture first, see Image Rotator.

Accepts JPG, PNG and WebP, identified by their contents. The result is in the same format. Limits: 20 MB, 12,000 px per side and 40 megapixels for the source image. GIF, BMP and animated WebP are not accepted. Only one rectangle can be kept per run.

1. Choose a JPG, PNG or WebP file (up to 20 MB).
2. Drag on the preview to draw the area to keep. Adjust X, Y, width and height if you need exact pixels.
3. Click "Crop Image" and download the result, named after your file with "-cropped" added.

• Cutting a border, margin or unwanted edge off a scan or screenshot
• Taking a square or tight crop of a face from a wider photo
• Cropping a photo to the exact pixel area a form or template specifies
• Trimming a screenshot before sharing it

Only rectangles, measured in whole pixels. There are no aspect-ratio presets such as 16:9 or 1:1, no circular or freeform crop, and no rotating of the box. JPG and WebP are saved again at quality 85, and camera data (EXIF, GPS) is not carried into the result. A crop box that extends past the picture is refused rather than adjusted.
