Add a watermark
Overlay a logo on a video. Pick the corner, the size and how transparent it sits.

PNG with transparency works best.

Preparing the logo
Use a PNG with a transparent background. A JPEG will paste a solid rectangle over your footage no matter what the opacity is set to. If your logo is white, it will disappear on bright scenes. A version with a soft dark outline survives more backgrounds.
Watermark width is in pixels of the output, not a percentage. On a 1920 wide video, 200 px is a discreet mark and 400 px is assertive. On a 720 wide video, 200 px is already large.
Opacity
Around 70 to 85% reads as a deliberate mark. Below 40% it becomes a smudge that survives neither re-encoding nor screenshots, which defeats the point.
What a watermark can and cannot do
It is worth being clear about this, because watermarking is often reached for with the wrong expectation. A visible mark deters casual reuse: someone lifting your clip for a compilation has to either leave your name on it or do visible work to remove it. That is a real effect and it is the whole of the benefit.
What it does not do is prevent theft. A determined person can crop it off, cover it, or blur it out, and automated tools do a passable job of all three. It also does not establish ownership in any legal sense; that comes from having the original file and a record of when you made it. Treat the mark as a signature and a nuisance to copiers, not as protection.
Placing it so it survives
Corners are conventional and are also the first thing a cropper removes. If the point is deterrence rather than decoration, put the mark somewhere a crop would have to destroy the shot to remove: across the lower third, or offset towards the centre. Against that, anything near the bottom of a vertical video will sit under the platform's own interface, where captions, usernames and buttons cover roughly the lower fifth of the screen on TikTok and Reels.
The compromise most people land on is upper third, offset from the corner. It is out of the way of platform furniture, visible, and awkward to crop out.
Making the logo work on any footage
A flat white logo vanishes on bright scenes and a flat black one vanishes on dark ones. A version with a soft outline or drop shadow in the opposite tone survives both, which is why broadcast bugs are almost always built that way. If you only have one version, mid-grey with an outline is the most forgiving.
The width is in pixels of the output, not a percentage, so the same setting reads very differently at different resolutions. On a 1920 wide export, 200 px is discreet and 400 px is assertive. On a 720 wide export, 200 px is already more than a quarter of the frame. Check the resolution with media info before choosing, and remember the mark will be seen at feed size, where anything too subtle simply disappears.
For text rather than an image, add text to video is the simpler tool, and the editor can move a mark around over the course of a clip.
Common questions
Can I put text instead of an image?
Yes, use add text to video, which draws text directly with no image needed.
Does the audio get re-encoded?
No. The audio stream is copied through untouched; only the picture is re-encoded.
Can I move the watermark around during the video?
Not in this tool. The position is fixed for the whole clip.
