About Image Cropper
Image Cropper cuts a PNG, JPEG or WebP image down to an exact pixel rectangle, measured from the top-left corner of the original. Instead of dragging handles, you type the Left offset, Top offset, Crop width and Crop height in pixels, and an outline on the preview shows the area that will be kept. Four preset buttons save time: Full image, Square, 4:3 and 16:9. Each preset picks the largest centered rectangle of that shape that fits inside your picture. The crop must stay inside the original and use whole pixels with a width and height of at least 1, otherwise an error appears and the Create image button is disabled. The output is exactly the size of the crop, with no resampling, so cropped pixels match the source. Choose PNG, JPEG or WebP as the output format; JPEG and WebP offer a quality slider from 10 to 100 percent. PNG and WebP keep transparency, while JPEG fills transparent areas with white. Files up to 25 MB and 12,000 pixels per side are supported. Nothing is uploaded, and the download is named after your file with -utilzilla added.
How to use Image Cropper
- Choose an image, then wait for the Original preview and its dimensions to appear.
- Pick a preset (Full image, Square, 4:3 or 16:9) or type your own Left offset, Top offset, Crop width and Crop height.
- Check that the outline on the preview covers the area you want, then set the Output format and Quality.
- Select Create image, review the Result, and choose Download image.
Frequently Asked Questions
Enter the Left offset and Top offset where the crop should start, then the Crop width and Crop height you want. The output matches those numbers exactly. All four values must be whole pixels and the rectangle must sit fully inside the original.
Use the Square, 4:3 or 16:9 buttons. Each one sets the largest centered rectangle of that shape that fits your image. You can then nudge the offsets or size by hand before creating the result.
The crop rectangle cannot extend past the image edges. The left offset plus the width must not exceed the image width, and the top offset plus the height must not exceed the image height. Reduce a value and the message clears.
Cropping itself does not resample pixels. Quality only changes if you export as JPEG or WebP, which are lossy and use the Quality slider. PNG is lossless. JPEG replaces transparent areas with white, while PNG and WebP preserve them.
