Crop an image

Yes, because there are fewer pixels to store. A crop that keeps half the area will usually produce a file somewhere near half the size, though the exact figure depends on how detailed the part you kept is.

Pick a ratio and the selection locks to it: dragging any handle keeps the shape, and dragging the box to an edge shrinks it rather than distorting it. The readout under the image shows the pixel size and the ratio of the current selection at all times.

No. Image Cropper runs entirely inside your browser using the Canvas API. The file is read from your device, processed on your device, and the result is handed straight back to you. It never travels to a server, so there is nothing for us to store, log or leak.

It is free with no account and no watermark. Because the work happens on your own hardware there is no per-image cost to us, so there is no quota. The only real limit is your device's memory: images beyond roughly 40 megapixels are refused rather than crashing the tab.

Yes. The tools work in any current mobile browser, and the result downloads to your camera roll or Files app like any other download. Very large images are slower on a phone than on a laptop because the processing is genuinely happening on the device.
