Celebrate National Humor Month in April by making your own reaction GIFs to add humor to your posts and multimedia all year long.

The site Unscreen lets you upload little video clips and remove the background. Film yourself pointing, clapping, dancing and thumbs-up-ing to make transparent GIFs (called stickers) that you can add to images and video. Removeit.io does the same and doesn’t add a watermark on the free versions.
