Multiple Face Swap

Most face swappers handle one face and make you run the image through repeatedly for the rest. PhotoHero detects every face in the shot at once and lets you decide, per person, whether to replace them and with whom.

Try it right here — no account, no card. Upload a group photo, tap the people you want changed, and give each one its own new face. Free runs come back watermarked; a free account removes the mark and brings the swap with you.

How it works

Upload the photo

Any shot with more than one person — group photos, couples, team pictures.

Map each face

Detected faces appear as separate targets. Assign a new face to each one you want changed.

Download once

One result with every selected swap applied — no repeated exports to stitch together.

How face detection handles a crowd

Detection runs across the whole frame rather than on a single dominant subject, so large group shots are found in full. Each detected face becomes its own target you can assign to, skip, or leave alone.

One run swaps up to 10 faces — each is a separate pass, so the cap stops a single job fanning out indefinitely. In practice you hit a different limit first: pixels. Faces are found reliably while they still occupy a reasonable share of the frame, and because images are normalized to a 1920px long edge, someone standing at the back of a wide group shot may be resolved into too few pixels to swap convincingly even when they are detected. Crop tighter on the people who matter and the results improve markedly.

When two people in the shot look alike

Targets are chosen visually, by clicking the face you mean, rather than by an ordering you have to guess at. That matters in exactly the case people find frustrating elsewhere: two similar-looking people in one photo, where an index-based tool silently swaps the wrong one and you only notice after generating.

If you swap the wrong person, the fix is to reassign and re-run rather than to start over — you are only charged for faces actually swapped.

Mixed angles are the real difficulty

In a group photo, people are rarely all facing the camera the same way. Someone turned three-quarters away will swap less convincingly than the person looking straight down the lens, using the same source face — that is a property of how much of the target face is visible, not a setting you can turn up.

The practical approach is to be selective: swap the front-facing people, leave the ones turned away, and the composite reads far better than swapping everyone indiscriminately.

Frequently asked questions

Is it really free, and do I need an account?+

You can swap multiple faces on this page with no account and no card — upload, pick the faces, and get the finished image at full resolution. Those free runs are limited to a few a day and come back with a "PREVIEW" watermark. A free account removes the mark, carries the swap you already made across clean, and includes 100 credits — about 100 more faces.

How many faces can I swap at once?+

Up to 10 in a single run — each swapped face is its own pass, so the cap keeps one job from fanning out indefinitely. In practice the binding limit is pixels, not the count: very small faces in a wide shot may be detected but lack the detail to swap convincingly.

How is multi-face swapping priced?+

Free runs on this page are limited per day. With an account, photos cost 1 credit per face you actually swap — swapping two of five people costs 2 credits — and video is 2 credits per second regardless of how many people you change.

Can I leave some faces unchanged?+

Yes, and this is the normal case. You pick exactly which detected faces to replace; everyone else is untouched, pixel for pixel.

Can I put a different face on each person?+

Yes. Each target is assigned independently, so you can map a different source face onto every person in the shot.

Does it work in video as well as photos?+

Yes — each person is tracked and swapped across every frame. Pricing there is per second of clip, not per face.
