GIF Face Swap
Put any face into an animated GIF and download a new GIF that keeps every movement.
Example · made with RegiAI Saved to your workspace history.
GIF Face Swap puts a face from a photo into an animated GIF and gives you back a new GIF that loops just like the original. The face is replaced in every frame, so it follows the head movements and expressions of the reaction you picked, and the hair, body and background stay the same.
It is built for reaction GIFs and short loops you want to drop into a group chat or a Slack channel. For a still picture, the photo AI Face Swap is faster and costs $0.10. For a real video file with an MP4 output, use AI Face Swap Video.

What happens to your GIF
A GIF is really a stack of small images. To swap the face in all of them at once, RegiAI converts your GIF to a short video, replaces the face frame by frame with the same model used for AI Face Swap Video, then turns the result back into a GIF.
The GIF you download is optimized for sharing: up to 420 pixels wide, 10 frames per second, with a tuned color palette, and it loops forever like most reaction GIFs. That keeps the file small enough for chat apps. GIFs have no sound, so there is no audio in the result.
If you need a larger or smoother file, swap the face in the original MP4 instead with AI Face Swap Video, which returns a 720p video. You can also pull a single frame from a GIF with the GIF to PNG converter and swap it as a still with AI Face Swap.
Picking a GIF that swaps well
The best GIFs for face swapping are the classic ones: one person, face on camera, clear expression. A few things to check before you upload:
- One main face. If two or more people are in the loop, the model may swap the wrong one.
- Big enough faces. Tiny faces in a wide shot do not carry much detail. Close-ups work best.
- Not too many cuts. A single continuous loop blends better than a GIF that jumps between shots.
- Similar angle in your face photo. A straight-on photo matches most reaction GIFs.
- Under 10 seconds. Longer GIFs are rejected. Most reaction GIFs are only 2 to 4 seconds.
Only use GIFs and faces you have the right to use, and never use a swap to deceive, harass or impersonate anyone.
Reaction GIFs, copyright and consent
Many popular reaction GIFs are cut from films, TV shows and music videos, and the person in them is a real actor or public figure. Swapping your own face into one for a private chat is a common joke, but the source footage still belongs to someone else. Keep swaps of copyrighted clips personal, and do not sell them or use them in ads.
The face you put in matters too. Only use your own face or the face of someone who agreed. You will be asked to confirm that you have permission before the tool runs. Do not use GIF Face Swap to mock, deceive, harass, impersonate or sexualize anyone, and do not make a GIF that puts words or actions on a real person that could be mistaken for real.
RegiAI does not add a watermark to your GIF. If you share it outside a group of friends, say that it is edited. Your GIFs are kept in My creations for 30 days, and you can delete them at any time.
