GIF Resize
Resize an animated GIF to any width while maintaining aspect ratio. All frames are resized in your browser.
Scale an animated GIF to any target width while automatically maintaining the aspect ratio. Resizing runs frame-by-frame in your browser using the Canvas API — no upload, no waiting.
