Crop an animated GIF image, photo or picture and keep it moving. Out comes a GIF whose every frame is cut to your box, with the original colours, frame delays and loop count copied across, so it plays exactly as before, just smaller.
Many croppers decode the first frame and save a still. Here each frame is cut out in its palette form, so no colour is re-chosen. Shapes, turns, resizing and file-size targets would need new pixels for every frame, so they pause the animation and the panel says which one did.
A still picture: crop photo. An exact pixel box: crop by pixels. A PNG with transparency: crop PNG.
What you can do here
Every frame, the same box
Each frame of the animation is cut to your box and moved by the same offset, so nothing jumps between frames.
Timing and loop copied
Frame delays, the loop count and how each frame is cleared are copied as they are, so it plays exactly as before.
Colours untouched
Frames are cut in their palette form: no colour is re-chosen and no dithering is added.
Honest when it cannot
A shape, a turn, a resize or a KB target needs new pixels for every frame, so the animation pauses and the panel says which setting did it.
How to gif cropper
- 1Open the GIF
Drop it on the box. The frames are read in this tab and counted.
- 2Drag the box
Frame it on the first frame; every other frame is cut to the same box.
- 3Download
The contract shows GIF, the frame count and the bytes. Download saves the animated GIF.
Questions about cropping
Are the frame delays and the loop kept?
Yes. Each frame keeps its own delay, the loop count is copied from the file, and the way each frame is cleared before the next one is kept too, so the cropped GIF plays at the same speed and loops the same number of times.
Are the colours changed?
No. A GIF stores each frame as numbers pointing into a colour table. The crop copies those numbers and the tables as they are, so no colour is re-chosen and no dithering is added.
Why is the cropped GIF not much smaller?
Each frame's cut-out is compressed again for its new size. Fewer pixels usually means fewer bytes, but GIF compression depends on the picture, so a crop of a busy area can keep a lot of its weight. The exact size is in the contract before you save.
Does it crop animated WebP?
Not as an animation yet. An animated WebP opens and its first frame can be cropped, and the contract says first frame only, so you are never handed a still while expecting an animation.
Is there a frame or size limit?
A GIF opens if its first frame is within 80 megapixels and the file within 150 MB. To keep the tab responsive, an animation whose frames add up to more than 400 million pixels, for example 400 frames at 1000×1000, is refused with a sentence.
Can I resize, rotate or shape a GIF?
Those need new pixels for every frame, which would mean choosing new colours. So they pause the animation: the panel names the setting, and only the first frame is saved until you undo it.
