How to Swap Faces in a Photo Online?
Swap faces in a photo online by choosing two pictures, marking the faces and letting a browser tool blend one face into the other. FaceSwapper handles this entirely inside your web browser, so there is nothing to install and no photo upload. This tutorial walks through each stage, from picking images to saving a polished result.
Before You Begin
Gather two photos: the original picture you want to change and a picture containing the face you want to use. Both should show the face clearly, ideally from a similar angle with comparable lighting. Clear, front-facing portraits produce the most natural swaps.
Use a recent browser on a computer, tablet or phone. The tool accepts JPG, PNG, WebP, GIF and BMP files up to 15 MB each, which covers photos from almost any camera or phone.
Adding Your Photos
Choose the Original Photo
Open the FaceSwapper tool and select the first step card, or drag a photo onto it. This is the picture that keeps its background, hair and clothing. A preview appears in the card, and the photo loads into the left editor with an oval ready to place.
Choose the Face Photo
Select the second step card and choose the photo containing the face you want to use. It appears in the right editor. If you want to practise first, press Try example photos to load two sample portraits with the ovals already in position.
Placing the Face Ovals
The ovals tell the tool which part of each photo to use. In the original photo, drag the oval over the face you want to replace. In the face photo, drag the oval over the face you want to bring across. Covering the same features in both photos is the key to a natural result.
- Centre each oval between the eyes, slightly above the nose.
- Cover from just above the eyebrows to just below the chin.
- Keep the oval inside the cheeks rather than over hair or ears.
- Use the tilt slider if a head leans to one side.
- Use arrow keys for precise movement, and plus or minus to resize.
Where your browser supports built-in face detection, a Find face button can place the oval automatically. You can still adjust it manually afterwards.
Adjusting the Blend Settings
The blend settings control how the new face merges into the original picture. Edge softness fades the boundary, face strength sets how strongly the new face replaces the old one and skin tone matching adjusts colour and brightness to suit the original photo.
| Setting | What it changes | Suggested start |
|---|---|---|
| Edge softness | Width of the faded edge | 30% |
| Face strength | Opacity of the new face | 100% |
| Skin tone matching | Colour and brightness balance | On |
Running the Swap and Reviewing It
Press Start Face Swapping. The result appears in the workspace within moments, created by your browser on the HTML canvas. Look closely at the eyes, mouth and edges. If something looks off, move an oval slightly, change the softness and run the swap again.
Common fixes are simple. A visible seam usually needs more softness or a slightly larger oval. A face that looks too bright or dark improves with skin tone matching turned on. Misaligned eyes mean the ovals cover different areas of the two faces.
Saving and Continuing
When you are happy, press Download Result to save a PNG named faceswapper-result.png. There is no watermark, and the file is created entirely on your device.
For group photos, press Edit result again to make the finished image the new original. Place the oval on the next person and repeat. Switch photos reverses the two pictures if you want to try the swap the other way round, and Clear all resets everything.
Sharing Responsibly
Only edit photos you have the right to use, and ask the people shown before changing or sharing their faces. Avoid impersonation, misleading posts or anything that could harm someone's reputation. Labelling an image as edited keeps the fun transparent.

Using Keyboard and Touch Controls
The editors respond to several kinds of input, so you can work in whatever way feels comfortable. On a computer, click a photo and use the arrow keys to move the oval in small steps, holding Shift for larger jumps. The plus and minus keys make the oval bigger or smaller.
On phones and tablets, drag the oval with one finger and use the sliders underneath each photo for size, height and tilt. The result looks the same whichever method you use, because all controls change the same oval.
| Action | Mouse or keyboard | Touch |
|---|---|---|
| Move oval | Drag or arrow keys | Drag with one finger |
| Resize oval | Face size slider or plus and minus | Face size slider |
| Change shape | Face height slider | Face height slider |
| Rotate oval | Tilt slider | Tilt slider |
Practising with Example Photos
The example photos are a quick way to learn the controls before using your own pictures. Load them, run the swap, then try moving the ovals or changing the softness to see how each setting affects the result. A few minutes of practice makes later edits much faster.
Troubleshooting Quick Reference
Most issues have simple causes. If the Start Face Swapping button stays inactive, check that both photos have loaded into their editors. When a photo fails to open, it may be in an unsupported format or larger than 15 MB, so try saving it as a JPG first.
If the download does not start, some mobile browsers open the image instead. Long-press the result image and choose to save it. Refreshing the page clears everything, so save results before reloading.
Conclusion
Swap faces in a photo online in a few steps: add two photos, place matching ovals, adjust the blend and download the result. Careful photo choice and oval placement do most of the work, while FaceSwapper handles mapping, colour matching and blending in your browser. Head to the face swap tool and try it with your own pictures.
