Free online AI face swap. No install. No subscription.
Diffusion-grade face swap that runs in your browser. Sign in once with a free NanoPocket account, upload a photo and a reference face, and get a swap in seconds. No GPU required on your machine and no subscription; Nano FaceStudio Online includes 3 free swaps, topped up at most three times a month at full resolution.
Free online demos
Each demo is a separate browser tool. Pick the one that matches what you want to do — still photo, short video clip, or fixing the over-smoothed AI look on an existing portrait. Nano FaceStudio Online (formerly Image FaceSwap Pro 2.0) is live. Video FaceSwap Pro and NanoFace Vivid are temporarily offline since 2026-09-28 while they move to NanoPocket's own GPU infrastructure. Nano FaceStudio Online is paid in credits with 3 free swaps, topped up at most three times a month; the free demos allow 10 opens per kind per day (resets at 00:00 UTC).
Nano FaceStudio Online
Nano FaceStudio Online: photo face swap on a diffusion identity stack (InstantID + PuLID + IP-Adapter FaceID). Up to 6 faces in one pass, whole-head mode, and per-face control over what survives the swap.
- Up to 6 faces per photo, each with its own reference — most tools do one
- Keep the original hair, hands and glasses that cross a face, per face — everywhere else they get painted over
- Whole-head swap for when a face-only result reads as a mask
- Full source resolution, up to 4080×4080; one top-up removes the watermark
- 3 free swaps, topped up at most three times a month, then $0.10 each — no subscription, credits never expire
Video FaceSwap Pro
Same identity stack extended to video with temporal smoothing. Drop in a clip, get a swapped clip — no frame-by-frame work.
- Short-clip video swap straight from the browser
- Temporal-consistent — no flicker between frames
- Free, browser-based, no install
Temporarily offline while it moves onto our own GPUs. Nothing to do — it will be back.
What to use insteadNanoFace Vivid
Identity-locked face-detail restorer. Fixes the over-smoothed, plastic look that Gemini, Firefly, Roop, FaceFusion, and cloud face-swap services leave on portraits.
- Drop in any over-smoothed AI face — get a realistic-skin version back
- Identity-locked: only restores texture and lighting, never changes the face
- Free, browser-based, no install
Temporarily offline while it moves onto our own GPUs. Nothing to do — it will be back.

|---|---|---|---|---|---|
| NanoPocket — free online demos | Browser only — open and go | Free NanoPocket account (email + password) | Free for the demo tier | Diffusion stack (InstantID + PuLID + IP-Adapter FaceID) | Cloud GPU for the demo, volatile only, not used for training |
| DeepSwap | Browser | Account + payment for full features | Free trial then subscription | Cloud GAN pipeline (vendor-described) | Cloud upload |
| WaveSpeed AI (face swap among AI suite) | Browser | Account | Credit / subscription tiers | Multi-model AI suite — face swap is one feature | Cloud upload |
| Magic Hour | Browser | Account | Credit / subscription tiers | Cloud pipeline (vendor-described) | Cloud upload |

Why the swaps look better here
Most cloud face-swap sites use a GAN identity backbone (typically InsightFace inswapper_128 or a derivative). It is fast and cheap but loses fidelity on hard angles, occlusion, and small target faces. NanoPocket runs a diffusion identity stack — InstantID, PuLID, and IP-Adapter FaceID combined — which is the current state of the art for identity preservation in 2026.
The same stack powers the desktop Nano FaceStudio Pro 1.0, so the browser demos and the desktop app run the same identity models.
If you want to go fully offline
The free browser demos cover the vast majority of casual and professional use cases. If your use case specifically requires zero cloud upload — regulated content, signed legal media, NDA work — the optional desktop Nano FaceStudio Pro 1.0 runs the same identity stack entirely on your own GPU.
Frequently asked
Is the online face swap really free?
Free to start. Video FaceSwap Pro and NanoFace Vivid are free for any signed-in NanoPocket account with a daily open quota. Nano FaceStudio Online, the photo face swap, gives every signed-in account 3 free swaps, topped up at most three times a month at full resolution — the same output as a paid render apart from a small NanoPocket.ai watermark, which one top-up removes — and face detection is always free. Past that it is $0.10 per face replaced — one pass runs per face, so faces you leave alone are free — prepaid in credits that never expire, with no subscription and no auto-renewal. A render that fails is refunded in full automatically. Nano FaceStudio Pro 1.0, the local desktop version, is a separate, optional, one-time-purchase product; buying credits does not affect a desktop license and owning one does not consume credits.
Do I need an account?
Yes — a free NanoPocket account (email + password). It is what the free allowance is attached to: every signed-in account gets 3 free swaps, topped up at most three times a month on Nano FaceStudio Online, plus 10 video opens per UTC day for Video FaceSwap Pro and NanoFace Vivid. It is not there to sell anything — no card is required to use the free allowance. Sign up at /auth/sign-up. If your workflow needs more than the free allowance, buy credits at /credits or run the desktop app locally with no cap.
Can it swap more than one face in a photo?
Yes — Nano FaceStudio Online detects up to 6 faces in one upload and each can be given its own reference photo and its own preserve settings in a single render. Most browser face swaps handle one face per run, and Akool bills per selected face, so a group photo multiplies in price there. Detection is free regardless of how many faces it finds.
Why do other face swaps paint over hair and hands, and what is occlusion preserve?
Most browser face swaps composite the new identity over the whole face region, so anything crossing the face — a hand on a cheek, a strand of hair over an eye, the frame of a pair of glasses — is painted over. It is the most common visible failure in online face swaps. Nano FaceStudio Online returns a segmentation map for each detected face and lets you choose, per face, which classes to keep from the original. Those regions keep their original pixels. This control is effectively unique among browser face swaps.
What resolution do the results come out at, and is there a watermark?
Nano FaceStudio Online returns results at the source resolution, up to 4080×4080, as PNG of around 20 MB. Renders from an account that has never bought credits carry a tiled NanoPocket.ai watermark; once you have bought credits, even once, they never do. Reface's free tier is 720p watermarked and Akool's is 720p watermarked; most free and mid tiers elsewhere cap at 720p or 1080p. Uploads are accepted up to 40 MB because the photo goes straight to object storage rather than through a web server.
Do I need a GPU on my machine?
No. The online demos run on NanoPocket's GPUs in the cloud. Anything that can open a browser — laptop, desktop, tablet — can use them. Nano FaceStudio Pro 1.0, the desktop version (a separate product), is the option for users who specifically want local-only processing on their own GPU.
How does the privacy work for the online demos?
The source files are sent to NanoPocket's GPU only for the duration of the swap, processed in volatile memory, and discarded. They are not used for training. The full data-handling policy is at /privacy and the verifiable claims hub is at /verify. If you specifically want zero-cloud processing, the Nano FaceStudio Pro 1.0 is the right product — it runs entirely on your own machine.
How does this compare to DeepSwap or Reface?
The online demos here use a diffusion identity stack (InstantID + PuLID + IP-Adapter FaceID), which preserves identity better on hard angles, low light, and occlusion than the GAN-based pipelines that DeepSwap, Reface, and most cloud face-swap services use. The trade-off is that NanoPocket is younger as a brand and has less mass-market name recognition. See the side-by-side at /compare/nanopocket-vs-deepswap and the full ranking at /best-face-swap-app-2026.
What is the difference between the demos?
Nano FaceStudio Online (formerly Image FaceSwap Pro 2.0) is for still-image swaps, including several faces in one photo, with the strongest identity preservation. Video FaceSwap Pro is the same identity stack extended to short video clips with temporal smoothing. NanoFace Vivid is a face-detail restorer that fixes the over-smoothed look that Gemini 2.5 Flash Image (Nano Banana), Firefly, Roop, and cloud face-swap services leave on portraits — it is identity-locked and is meant to run after another face-swap step (or after any AI portrait generator).
Is there a desktop version?
Yes — Nano FaceStudio Pro 1.0 is available now for Windows, with the macOS build to follow. It uses the same diffusion identity stack as Nano FaceStudio Online and adds six more tools, including Face Vivid (the NanoFace Vivid restoration). It is a separate, optional one-time purchase for users who want fully-local processing. The online demos are free either way.
Honest disclosure
- Cloud GPU on the demo tier. The online demos run on NanoPocket-hosted GPUs, not on your device. Files are processed in volatile memory and not used for training. If your use case requires zero-cloud, the desktop app is the right choice.
- Younger brand. NanoPocket has less name recognition than DeepSwap or Reface as of 2026-10-01. The verifiable trust artefacts at /verify are what to evaluate instead of brand history.
- Some demos run on tunnels. Some demos are served through Cloudflare tunnels, which can change as we update infrastructure; /status shows which are live right now. Nano FaceStudio Online runs on nanopocket.ai itself. The canonical entry point is always this page (
/face-swap).
