- Logos, landscapes and text screenshots will not work
Videos up to 300s (90s with enhancement on)
Plate armor, a sword and a castle wall — put your face on a medieval knight with the visor up. This knight face swap tool takes two uploads and one button. The first upload is the face — yours, or the face of someone who agreed to it. The second is the target: the photo or video the face should land on. The engine finds the face in the target, replaces it, and keeps the costume, the background, the lighting and the motion of the original.
Knight targets are reenactment photos, medieval-fair shots and historical-film stills. The helmet has to be off or the visor up, so the whole face shows. A closed great helm leaves nothing to swap.
An image swap costs 15 credits and usually finishes in seconds. A video swap costs 20 credits because every frame gets its own detection pass; short clips typically land in one to five minutes. A failed job refunds its credits automatically, and nothing you make is published to a gallery.
What This Knight Face Swap Tool Does
You choose both faces
No preset templates you cannot change. Bring your own target — a costume photo, a movie still, a stock shot, a clip from your phone — and your own source face.
Photos and videos, same engine
A still knight face swap costs 15 credits. A video costs 20 and tracks the face through motion, talking and head turns, frame by frame.
Optional face enhancement
Face enhance restores skin texture and eye detail after the swap. Frame enhance upscales a soft target. Neither changes the credit price.
Advanced controls when the light is hard
Swapper model, pixel boost, detector score, mask blur and output quality sit in the advanced panel. Most targets never need them; heavy makeup, masks and stage lighting sometimes do.
Private processing
Uploads go to private storage and are used only to run your job. Results are not posted anywhere, and you decide what leaves your device.
How to Make Your Knight Face Swap
Upload your face
A front-facing photo with both eyes visible, even light and nothing covering the face. One person in the frame.
Upload the target
The photo or video the face should land on. The face in it should be uncovered and at least a few hundred pixels wide.
Swap and download
Press the button. Images return in seconds, videos in minutes. Download the result, or adjust a setting and run it again.
Videos up to 300 seconds work with enhancement off. With face or frame enhancement on, the limit is 90 seconds, because every frame is processed twice.
Ideas for Your Knight Face Swap
The same two uploads cover very different jobs. These are the most common ones for this theme.
Reenactment portrait
A formal knight portrait with your face, for a reenactment group or a fair poster.
Tabletop character art
A paladin or knight portrait for your role-play character that actually looks like you.
History lesson hook
A teacher swaps their own face onto a knight to open a lesson on the Middle Ages.
Getting a Clean Knight Swap
Pick a target the swapper can read
The engine replaces a face it can detect. If the target shows the face in profile, behind a visor, under a mask or smaller than a thumbnail, there is nothing to replace, and the job fails or the result looks pasted on. A three-quarter or frontal face in the target swaps best.
Resolution matters more than file size. A face that is 300 pixels wide in the target gives the model room to rebuild eyes and teeth. A 60-pixel face in a wide group shot does not, however sharp the rest of the frame is.
Where Knight Swaps Go Wrong
Most failed swaps are not model failures. They are a mismatch between the source and the target: a smiling source on a screaming target, a face lit from the left on a scene lit from the right, a pale source under orange stage light.
Armor reflects light up into the face, and medieval films are often shot in grey daylight with lots of grain. If your swap looks too clean, turn off face enhance and let the target’s texture through.
Photo first, then video
Test the pairing on a single frame before you spend credits on a clip. Take a screenshot of the video at the moment the face is clearest and swap that. If the still looks right, the video will look right.
For video, shorter is better. Trim the clip to the seconds you need, keep the face in frame, and avoid cuts that jump to a different angle mid-shot.
What Changes the Result
The source photo decides identity: the face shape, the eyes, the mouth. The target decides everything else: costume, pose, lighting, background, motion. So the source should be as plain as possible, and the target should carry all the drama.
If a swap looks flat, turn on face enhance. If the edge of the face shows a seam, raise mask blur slightly in the advanced panel. If the wrong face in a group shot was replaced, crop the target to the one person first.
- Source face is front-facing with both eyes visible
- No sunglasses, mask or hand covering the source face
- The face in the target is uncovered and not in profile
- Lighting direction is roughly the same in both uploads
- Video is trimmed to the seconds you need
- You have permission from everyone whose face you use
Consent and Labeling
Use your own face, or the face of someone who said yes. A swap for a party, a card or a costume idea is fine. Putting a real person into a scene they did not agree to, sexualizing anyone, or making a swap look like real evidence is not, and the terms of service ban it.
If you publish a swap, label it as AI-generated. In the EU that is a legal duty under Article 50(4) of the AI Act, and on every platform it is the honest thing to do. The aideepfake.io watermark stays on by default until your first purchase.
Knight Face Swap FAQ
Is this knight face swap tool free?
A guest gets 15 trial credits once, enough for one image swap. A free account then gets 15 credits every day. An image swap costs 15 credits and a video swap 20.
Do I need to install an app?
No. The tool runs in the browser on desktop and mobile. You upload two files, press the button and download the result.
Can I swap a face into a video, not just a photo?
Yes. Upload a video as the target. Up to 300 seconds works with enhancement off, 90 seconds with enhancement on, and a video swap costs 20 credits.
Will there be a watermark?
Renders carry an aideepfake.io watermark by default. Any purchase — a credit pack or a subscription — unlocks the switch that removes it.
What happens to my photos?
They are stored privately, used only to run your job, and never published to a gallery. A failed job refunds its credits automatically.
Can I swap my face onto a knight in a closed helmet?
No. The swapper needs to see the face. Use a target with the helmet off or the visor raised.
Will the armor look real after the swap?
The armor is not touched. Only the face area changes, so the armor stays exactly as it is in the target.
