Portrait creators
Test how a face reads in a new pose, outfit, or lighting setup without rebuilding the entire portrait.
You get a quick concept image for selecting the strongest direction.
Portrait editing
Use image face swap to place a different face into a still photo while preserving the pose, lighting, and overall composition. Wavespeed helps you explore a visual direction before committing to a finished edit.
Use cases
Still-image swapping is useful when the subject stays in one frame and you want a focused result that is easy to inspect, share, or revise.
Test how a face reads in a new pose, outfit, or lighting setup without rebuilding the entire portrait.
You get a quick concept image for selecting the strongest direction.
Prepare alternate campaign visuals from a controlled source image and a separate reference face.
You can compare several still concepts before producing a larger content set.
Explore a retouching idea while keeping the original framing, background, and styling intact.
The swap becomes a visual proof rather than a replacement for the original file.
Create a side-by-side presentation showing how a face change affects the mood of a composition.
A clear before-and-after makes review with clients or teammates easier.
Format comparison
A still source gives the model one composition to solve. Compared with moving footage, that narrower task usually makes inspection and correction more direct.
| Still-image swap | Video face swap | |
|---|---|---|
| Primary input | One source image and one reference face | A video clip plus a reference face |
| Main strength | Focused portrait or single-frame editing | Maintaining a face across motion |
| Review process | Inspect one finished frame | Check consistency across many frames |
| Best for | Portrait concepts, thumbnails, and static campaigns | Clips, reels, scenes, and moving subjects |
| Common challenge | Hair, glasses, hands, and unusual angles | Motion blur, fast turns, and changing light |
| Output focus | A single polished visual direction | Temporal consistency through a sequence |
| Useful next step | Compare alternate stills before publishing | Review the full clip for frame-to-frame stability |
Visual check
Use the divider to compare the source and result in one frame. Look first at alignment, then at edges, skin tone, hair, and any accessory that crosses the face.

Know the limits
A still-image workflow is powerful for controlled portraits, but it does not remove the need for judgment, consent, or careful final review.
Extreme profiles, covered faces, heavy shadows, or very small subjects can leave visible seams or weak facial detail.
What to do instead
Use a clearer source with a similar angle, crop, and lighting direction.
A result may resemble the reference without matching every expression, feature, or proportion precisely.
What to do instead
Treat the output as a concept and compare it with the source before sharing.
Glasses, hats, hair crossing the face, hands, and foreground objects may be altered or blended.
What to do instead
Choose a simpler frame or retouch those areas separately.
Technical success does not establish permission to use a person's likeness or publish the result.
What to do instead
Use your own images or obtain clear permission from the people represented.
Make a first pass
Bring a source image and a reference face, describe the edit you want, and review the result against the original. Start with a simple, well-lit frame for the most useful first test.
Variant FAQ
These answers cover the practical decisions that matter most when working with a source image and a reference face.
Choose a sharp image with a clearly visible face, even lighting, and a pose close to the reference. Front-facing or gently angled portraits are usually easier to assess than extreme profiles.
Use a reference image that you have permission to edit and publish. Similar camera angle, expression, and lighting can make the result look more coherent, but they cannot guarantee a perfect match.
The workflow is designed around changing the face within a still composition, so the background and pose may remain visually consistent. Review hair, glasses, shadows, and objects crossing the face because those areas can change during the edit.
Compare the edited image with the original at full size and zoom in around the jawline, eyes, hairline, and ears. Also confirm that the image is clearly labeled or used with appropriate consent when another person's likeness is involved.
