What does Add Watermark to Video do?
Add Watermark to Video places an image you choose over a local video. Drag the preview, use a corner or center preset, or nudge it with the keyboard controls. Scale, opacity, margin and the start and end time are applied during export. The picture is re-encoded as MP4 and the audio track is kept. Tubelexity does not stamp its own logo onto the file.

Practical uses

Browser and media limitations

- Audio is kept as AAC when a track is present.
- Very large videos can run out of browser memory.
- The media engine downloads the first time you export.
How local processing works
Your media is processed in this browser tab, not uploaded to a processing server. The media engine downloads on first export. Page navigation and analytics still use network requests. Download the result before closing the tab.
Frequently asked questions
Does Tubelexity add its own watermark?
No. The overlay is the image you upload. The page does not stamp a Tubelexity logo.
Is the video uploaded?
No. The video and the watermark image stay in this browser tab.
Can I keep the original audio?
Yes. The export maps the first audio track when the file has one.
Why is the file re-encoded?
An image overlay has to be drawn into the picture. The result is H.264 video, not a copy of the original frames.
