Three swaps, three different edges to solve
Hair volume, glasses and head shape expose whether a tool really replaces the whole head.

How the AI head swap workflow runs
Four steps from upload to result. Same flow as the face-swap variant, except Head Swap replaces the full silhouette rather than only the face region.
| Step | Action | What matters |
|---|---|---|
| 1. Target photo | Upload the photo you want to keep as base scene, pose, and body. | Pick a clean composition with a clearly framed head area. Avoid heavy occlusion. |
| 2. Source head photo | Upload a second portrait containing the head and identity to transfer. | High-resolution, even lighting, visible landmarks. Match the head angle of the target if possible. |
| 3. Choose Swap Head | Select the Swap Head preset in Image Studio. | No prompt writing. The preset handles the silhouette, hair, and identity transfer. |
| 4. Generate | Make head swap — Uses 25 credits with GPT Image 2. JPG, PNG or WebP, up to 10 MB per image. | Iterate on the source image if the first result misses hair or jawline detail. |

Head swap vs face swap: which one fits your photo?
Case 1
You want the hairline and head shape from the source
Pick head swap. It replaces the full silhouette so hair, hairline, ear position, and jawline come from the source identity.
Case 2
You only want a different face on the same hair
Pick face swap. It keeps the original hair, head outline, and accessories and changes only the facial region.
Case 3
You are stitching identity across a series
Run head swap once per target to keep the identity consistent across multiple scenes, then optionally finish with face swap for fine-tuning.
What this head swap tool does and does not do
Head swap tools differ in how much of the head they replace and what a result costs. Before you upload anything, here is the scope of this page's tool in plain rows.
| Question | This tool |
|---|---|
| How much of the head is replaced? | The full silhouette: face, hair, hairline, ears and head shape come from the source photo. Only the body, pose, clothing and background stay from the target photo. |
| Do you write a prompt? | No. The Swap Head preset in Image Studio handles the transfer; you upload a target photo and a source head. |
| What does a swap cost? | 25 credits per swap, shown before you generate. New accounts build a small welcome balance day by day in the first week, and that balance tops out below the price of one swap, so plan a starter credit package for your first result. |
| Does it work on video? | Photos only today. For identity changes inside a video clip, see character swap AI, which swaps a person inside a generated video. |
| Does it work on group photos? | The swap is built for photos with one clear subject: there is no per-person selection in a group photo today. |
Three seams that give a head swap away
A head swapping tool can only blend what the two pictures allow. Most failed swaps break at one of these three places, and you can fix all three before you upload.
| Where it breaks | What you see | What to change in your photos |
|---|---|---|
| Head angle and light | The new head looks pasted on, lit from another side or turned a different way than the body. | Pick a source head with roughly the same turn and camera distance as the target. Light from the same side helps more than a higher resolution. |
| Hairline | Hair ends in a hard edge or old hair shows through behind the new head. | Use a source photo where the hairline is visible: no hat, no sunglasses pushed up, no hand in the hair. A target with short or tied-back hair leaves less to cover. |
| Neck and skin tone | A visible line under the jaw, or a face that is warmer or paler than the neck. | Pick photos taken in similar light, then zoom in on the neck before you download. If the seam shows, a second run with a closer match costs another 25 credits, so swap the photo first. |
FAQ
What is an AI head swap?
An AI head swap replaces the full head from a target photo (silhouette, hairline, ears, and face) with the head from a source photo. It is a stronger transformation than face swap, which only changes the facial region while keeping the original head shape and hair.
How is head swap different from face swap?
Face swap replaces only the face area and preserves the original head, hair, and outline. Head swap replaces the entire head silhouette, which is the right choice when hair style, head angle, or jawline of the source identity must come through.
How much does the UlazAI head swap cost per generation?
The tool runs at a fixed 25 credits per generated image, shown before you generate. A starter credit package covers many swaps, and the exact amount is confirmed in the generate response.
Which AI model powers UlazAI head swap?
Head Swap inside UlazAI Image Studio is powered by GPT Image 2, a premium identity-preserving image pipeline tuned for clean head and hairline transfer without prompt writing.
What photos work best for AI head swap results?
Use high-resolution portraits with clear lighting, visible facial landmarks, and a head angle close to the target. Avoid heavy occlusion, motion blur, and extreme side profiles for the strongest identity transfer.
Does the head swap keep the original hair?
No. A full head swap replaces the entire head including hair and hairline, so the result carries the source person's hairstyle. If you want to keep the target photo's hair and change only the face, use a face swap instead; the face swap vs head swap guide shows which one fits your photo.
Do I need a credit package for my first head swap?
Each swap costs 25 credits and the price is shown before you generate. New accounts build a small welcome balance day by day during the first week, and that balance tops out below the price of one swap, so plan a starter credit package for your first result.
Can I run an AI head swap on a video?
The UlazAI head swap tool works on photos only today. To transfer identity inside a video clip, use the character swap workflow, which swaps a person inside a generated video instead of a still photo.
Is "headswap" (one word) the same as head swap?
Yes. People write it as headswap in one word, or search for a head swapper, head changer, or head replacement tool. All of these describe the same edit: the whole head, hair and hairline included, moves from the source photo onto the target photo. If you only want a different face on the existing hair, the face swap guide is the better fit.
Is there a head swap app, or does it run in the browser?
It runs in the browser. You open this page or Image Studio on a laptop or phone, upload the two pictures and download the result. There is nothing to install.
Does the head swap work on group photos?
The swap is built for photos with one clear subject: you pick a target photo and one source head. There is no per-person selection inside a group photo today.

Swap the full head when a face-only edit is not enough
A head swap should carry the face, hairline and overall head shape into the target photo. Use a clear source portrait and a target with a similar camera angle; heavy occlusion around hair or hats makes the join less convincing.
Inspect the neck edge, ears and lighting before exporting. Those three areas expose a weak composite faster than the face itself.
