One editor for every GIF tool
This page is part of a full GIF editor. After you apply a change, switch tabs to keep going — crop, then resize, add text, change the speed, and optimize — without downloading and re-uploading in between. Undo and redo work across every tool, and your animation stays loaded if you open another GIF tool page.
Everything runs in your browser. Your files are never uploaded.
