The micro-blogging website Tumblr and the animated GIF may be two peas in a pod, but sometimes larger GIFs will not animate properly because of Tumblr's limit on their file size. Tumblr limits GIFs to 1 megabyte or less and sets limitations on the width of the image by not properly displaying GIFs greater than 500 pixels wide. Several free online services exist that allow users to reduce the size of GIFs so the animation will work properly on Tumblr.
