Crop Image

How it works

1. Upload. Choose the image to crop (up to 25 MB).
2. Set the area. Enter X and Y for the top-left corner and the width and height of the crop, all in pixels.
3. Download. The cropped image downloads automatically in its original format.

About this tool

Crop an image down to exactly the rectangle you want by entering the area in pixels — the X and Y of the top-left corner and the width and height. It's precise rather than guesswork: ideal for trimming a fixed margin, cutting a banner to an exact size, or removing an unwanted edge. The crop keeps the original file format, so a PNG stays a PNG and a JPG stays a JPG, and pixels are copied untouched so nothing is re-compressed. No watermark, no signup, processed in memory and discarded.

What people use it for

• Trim a fixed margin or border off a screenshot
• Cut an image to an exact banner or thumbnail size
• Remove an unwanted edge or object at the side
• Square-crop a photo to precise dimensions
