GIFs can be up to six seconds. To make sure your GIFs are viewable across your marketing channels and retain the best quality, use our GIF maker to create them with the proper specs. Square GIFs are best, with an ideal size of 480 pixels by 480 pixels, although a 3:2 or 2:3 aspect ratio also works. In general, you’ll want to keep them under 100 MB in size to avoid compression that can reduce their quality. The more frames per second, the larger the GIF file size, so aim for 15 to 24 frames per second.
