This image cropper trims an image down to just the part you want, without installing an editor. Drop in a PNG, JPEG, WebP, GIF, or BMP file and a crop box appears over the preview — drag it to reposition, resize it from the handles, or nudge it a pixel at a time with the arrow keys for precise framing. Lock the box to a fixed aspect ratio when you need a standard shape such as a square profile picture, a 16:9 thumbnail, or a 4:3 photo, or leave it free and crop to whatever region suits the image. The width and height of the selection are shown as you drag, so you can hit an exact pixel size, and the cropped result previews live beside the source. When you are happy, export as PNG for lossless quality and transparency, or as JPEG or WebP with a quality slider when file size matters, and the panel shows the resulting size before you download. All of the work is done locally with the browser canvas, so your image is never uploaded to a server — safe for screenshots, documents, and client material. Upload an image below to start cropping.

Frequently asked questions
How do I crop an image to a square?
Choose the 1:1 aspect-ratio preset. The crop box locks to a square that you can drag and resize over the image, and the exported result is perfectly square — useful for profile pictures and avatars.
Can I crop to exact pixel dimensions?
Yes. The crop box shows its width and height in pixels as you drag, and the arrow keys nudge it one pixel at a time so you can land on an exact size.
Does cropping reduce image quality?
No. Cropping only discards pixels outside the selection; the pixels you keep are unchanged. Quality is affected only by the export format — PNG is lossless, while JPEG and WebP re-encode with the quality you choose.
What image formats can I crop?
You can upload PNG, JPEG, WebP, GIF, and BMP files, and export the cropped result as PNG, JPEG, or WebP.
Are my images uploaded anywhere?
No. Cropping runs entirely in your browser using the canvas API, so the image never leaves your device and is never stored on a server.
Can I undo a crop?
The crop is non-destructive until you download: the original stays loaded, so you can move or resize the crop box freely and the preview updates each time. Nothing is written back over your source file.
