The box is drawn on the first frame — the crop applies to all of them.
one box, every frame
A crop on a still image is one operation. On a GIF it is one operation repeated across every frame, and the frames are not independent pictures: a GIF stores most frames as a patch that only repaints the pixels that changed since the last one, positioned somewhere inside the canvas. Cut those patches individually and the animation falls apart.
So each frame is composited to a full picture first, in order, honouring the disposal rules that say whether the previous frame stays underneath or gets cleared. Only then is the same rectangle taken out of each one and the animation rebuilt. You drag one box on the first frame; the rest follows exactly.
three steps
The first frame appears with a crop box on it. Drag the box or its corners; pick a fixed ratio if you need one.
Every frame is cut to that rectangle and the animation is rebuilt. The result size and duration appear next to it.
The cropped GIF is saved straight from the page.
quick answers
Because dragging a box against moving pixels is unusable — handles and content fight each other. The box sits on the first frame, and the rectangle you choose is applied to every frame at full resolution when the animation is rebuilt.
Yes. Frame count, per-frame delays and the loop setting all come through. Only the canvas gets smaller.
Not in the box itself — but the rebuilt animation appears as soon as you let go, so you can check the whole clip and drag again if something important left the frame.
Yes: 1:1, 4:3, 3:2 and 16:9 lock the box, and free lets you drag anything. The pixel size of the crop is shown under the image as you drag.
Usually, since there are fewer pixels per frame, but GIF size is driven by how much changes between frames as much as by dimensions. Cropping to a busy region can save less than you expect.
No. Decoding, cropping and re-encoding all happen in your browser. The file never leaves your device, so nothing lands in someone else’s logs.
