Add text over animated gif
This image text editor allows you to write your text over an animated gif image without losing the animation (you can use it to place captions on any non-animated images as well, if you want to). You can choose from several fonts and predefined positions on the image.
* This number is max font size. If the text will not fit within the boundaries, it will be reduced automatically.
