So I used ezgif.com to make my gif signure! You will also need superimpose or picsart and a text app.It seems like it would Be hard but it's easy! I'll have the link for ezgif.com in the comments! Now on to the tutorial! 

1. Once you open ezgif.com the page will look like this to upload a gif click gif resize tool. And it will take you to an uploading page.

2. Once the page loads click choose file and it will ask you if you wanna up load from camera roll or go to camera. Chose your gif and then click the upload button!

3. Now with the resizing tool you can change the size of your gif I didn't use this for mine but just to show how to use it click which ever part u wanna change width or height then type in the size of your choice next click resize it.

4. Once you click resize it under the if you scroll down alittle it will show u your resized gif and give you more options I went to crop.

5. Now to crop your image there is a box you can move and make the crop whatever way you'd like once finished you may click crop it and it will show u your cropped image if you don't like the crop just go back up and change the crop until you  like it. Then You can choose another  editing tool i went to overlay. But before you do press and hold on your cropped image to save it you need it for the next step.

6. Now before you upload anything go to superimpose or picsart. For superimpose open your gif then the color of your choice make the color over the gif and merge it to it then save. Next open your gif again and the one u just saved go to mask and use the lasso tool turn the smoothness all the way up lasso the part u wanna keep and then fix it however your like save as a png after your done.

For picsart open the gif and go to draw pick your color and turn the smoothness on the brush all the way up color it in how ever you'd like. Then deleted the gif and save the color part.

7. Now go to you text app I used phonto open your color u made and add your text to make sure it stays a png when you save your image click save as png. Then go back to ezgif.com

8.Now in overlay click choose file and pick the edit you made it will show u what your gif looks like with it on but then you need to click generate image it will show you the different options again you may do whatever else you'd like.
