Expression Swapping

One expression. Any face.

Choose an expression template — or copy from any photo — and transfer it to any target face. Blend sliders let you go from subtle to full replacement.

Zara Silly 2 is a free template — no Premium needed. Five diverse characters, thirty expressions each.

Built-in Template Library

30 expressions × 5 diverse characters. 10 expressions per character are completely free.

Blend, Don't Just Swap

Eye, mouth, and head-position sliders let you mix any fraction of the expression — subtle to exaggerated.

Face Reinsertion

Place the blended result back into the original photo seamlessly for natural, in-context output.

Selfie Correction

Fix an asymmetric face naturally

Use a mirrored copy of a face as the expression source and blend halfway between original and mirror. Uneven smiles, misaligned eyes, and crooked expressions visibly improve — while the natural look is preserved.

Before
Face after asymmetry correction
After

Uneven smile and misaligned eyes corrected with full-mirror blending (0.5 on all blend sliders). The resulting expression looks natural and balanced.

Full correction

Asymmetric face — before (example 2)
Before
Asymmetric face — after full correction (example 2)
After

Full mirroring (0.5) works best when the face is relatively upright and the expression is compatible.

Partial correction — expression preserved

Asymmetric face — after partial correction
After

Partial mirroring (0.2) reduces the crooked mouth while keeping the natural head tilt and expression intact.

Your face never leaves your phone

All processing runs entirely on-device using ONNX Runtime inference. No photos are uploaded, no face data is transmitted, and no account is required. Face2FaceAI is designed privacy-first from the ground up — your images stay yours.
