# Choosing a face swap tool

What separates face-swap tools, why the source photo matters more than the tool, and the consent and privacy checks that come first.

## What actually differs between tools

  - **Photo versus video.** Video needs a correct result on every frame _and_ consistency between them — a different, harder problem.
  - **Whether the target can be generated.** Dedicated tools need an existing image; platforms can create one.
  - **Identity across a set**, for persona work rather than one-offs.
  - **Retention and rights over uploads** — the difference that matters most and is advertised least.

## The thing that decides quality

Not the tool. A sharp, evenly lit, front-facing source photo with nothing crossing the face beats every setting change available, in every tool. Most people switching tools to fix a bad swap get the same bad swap, because the input was the limit.

Failure modes map to inputs: waxy skin means a low-resolution or already-retouched source; a visible hairline seam means hairstyles differ too much; flicker in video means the target clip has motion faster than the pipeline tracks; and "looks like a different person" means the source was too far from front-on. The [face swap guide](https://higgsfield.wiki/face-swap/) covers each.

## Check before uploading a face

  - How long are uploads retained?
  - Are they used for training?
  - Is there a real deletion mechanism, or only a policy?
  - Does free output carry a watermark?

**Consent is the first requirement, not the last.** Use faces you own or have explicit written permission for. Non-consensual and sexual deepfakes are illegal in many jurisdictions and prohibited by every mainstream provider.

## Common questions

### Which face swap tool is most realistic?

Realism tracks the source photo more than the tool. Sharp, evenly lit, front-facing, unobstructed beats any tool change.

### Are free face swap tools safe?

Depends entirely on retention and training terms, since your photo goes to their servers. Read them before uploading anyone else's face.
