Crop image
Drag a crop box on one image, pick a ratio like square or 16:9 for many, or enter an exact pixel rectangle. Processed locally.
First run downloads the conversion engine (about 4 MB) once, then it is cached.
The largest 1:1 area is cut from each image. Add a single image to drag the crop box yourself.
Advanced options
Crop one image or a whole batch
Add a single image and a crop box appears: drag it to move, drag the corner to resize, or pick a fixed ratio such as square or 16:9. Add several images and the same aspect ratio is cut from each one, anchored to the centre, top, bottom, left or right. Exact pixels mode applies the same rectangle to every file, which is handy for screenshots.

Frequently asked questions
Can I crop several images at once?
Yes. Choose an aspect ratio and where to anchor it (centre, top, bottom, left, right); the largest matching area is cut from each image. Exact pixels applies one rectangle to all.
Will the crop be exact?
Yes. The rectangle is applied in source pixels with no resampling, so the cropped area is pixel-for-pixel identical to the original.
Are my images uploaded?
No. The tool runs inside your browser with WebAssembly. Photos never leave your device, so it is safe for IDs, documents and private pictures.
