You can select the action to perform if the aspect ratio of the source image and your chosen size does not match - center and crop the image, stretch the image to fit, or force the original aspect ratio.
Gifsicle is usually the fastest tool and produces smaller files, but is designed for speed, not quality. Try different resize methods if you are not satisfied with the result. Some gifs may need the 'coalesce' option (which removes all optimizations from frames) if other methods fail and the output image is flickering or has strange artifacts, but it may significantly increase file size and is very slow. GIF animation resizing is sometimes tricky, and you will probably have to choose between a smaller file size or image quality.
Useful when you need to reduce GIF size or fit the image in specific dimensions.
Ezgif's online image resizer will resize, crop, or flip animated gifs and other images, with the same quality and speed as professional software, without the need to buy and install anything.
