How to Get TikTok's Shapeshifting Filter as Feature Is Rolled Out to U.S. On 4/14/21 at 11:42 AM EDT TikTok's shapeshifting filter is going viral again as the filter has now become available in the U.S. and Canada. The TikTok filter sees users upload an image of a person and then record themselves. The filter will then transition between the two. The filter has been used in numerous trends, including one that sees TikTok users share their celebrity lookalikes, and another that sees users prank a family member or friend into thinking the filter has selected a less-than-flattering celebrity doppelganger for them.
