Trim away everything outside the part of the GIF you care about. Drag a crop box straight on the animation, use aspect-ratio presets, and bake the crop without disturbing frame timing.
Cropping is often the single biggest file-size win — fewer pixels per frame means a smaller GIF before you've touched a quality dial.
Every pixel you crop away is a pixel that no longer has to be stored in every single frame, so trimming a GIF to just the part that matters often cuts the file size more than any quality dial. It is also the fix for a GIF that was captured with too much empty space around the subject.
pixelpix keeps the animation and its timing perfectly intact while cropping — GIF frames are usually stored as differences from the previous frame, and the tool handles that correctly so the cropped result plays cleanly with no ghosting or holes.
Like every pixelpix tool, this runs 100% in your browser: your file is never uploaded to a server, never leaves your device, and works even offline once the page has loaded.
