Crop GIF
Drag the frame over the part worth keeping. Cropping cuts pixels out of every frame at once, so it is also the cheapest way to make a GIF lighter.
Aspect ratio
1:1 for avatars and stickers, 4:5 for feeds, 16:9 for anything that plays like video.
— · drag the frame to move it, grab a corner to resize.

Cropping is the cheapest way to make a GIF smaller
Every pixel you cut away is removed from every single frame. Trim 30% off the width and height of a hundred-frame GIF and you have deleted half the file, without touching colours, frame rate or the smoothness of the motion.
That makes cropping the first thing to try when something is a few hundred kilobytes over a limit — ahead of the compressor, which has to start taking quality away.
Picking a ratio
1:1 is what avatar and sticker slots want; anything else gets squashed or auto-cropped by the platform, usually in the wrong place. 4:5 is the tallest shape most social feeds will show without cropping it themselves. 16:9 suits footage that came from video in the first place. Free is for the common case: there is dead space around the subject and you just want it gone.
With a ratio locked, the frame keeps its shape as you drag a corner, so you cannot accidentally end up at 1:1.04 and wonder why the platform re-cropped your sticker.
Questions
Does the animation survive cropping?
Yes. Every frame is cropped identically, the timing is untouched and the loop stays infinite. The palette is rebuilt from what remains, which sometimes makes colours slightly cleaner than the original.
Can I crop and resize in one go?
Not in one pass — crop here first, then run the result through the resizer. Both steps happen on your device, so there is no upload between them.
Is anything uploaded?
No. The GIF is decoded and re-encoded inside this browser tab.
The frame will not go where I want it.
The selection is clamped to the edges of the picture, and with a ratio locked it also keeps its shape. Switch to Free if you need an arbitrary rectangle.
