Hello,

As you could see toolxox com could add some emojis to your GIF images but it could lose animation.

Step 1:

Create a blank image with the GIF image so if your one is 440*350px then make it 440*350px blank.

Step 2:

Add a GIF to image at the place you would so.

Step 3:

Go to remove bg to remove background.

sThen click on Modifier after change background:

Go to EZGIF and overlay transparent emoji background to the animated GIF and this works like a charm, not adding background from remove bg as would not work.
