Video watermark overlay
Add a watermark to video online
Upload a video, add a text or logo watermark, choose position, opacity, size and the time range, then download the rendered MP4.
The service renders the result on the server, so the final file contains the watermark instead of only showing a browser preview.
✓
Browser-side media tools are useful for quick analysis, previews and lightweight exports.
✓
Large video and audio files may need time to decode; smaller samples work faster in the browser.
✓
When the result is a command, run it on a machine with the required media tools or model installed.
✓
Review generated WAV, PNG, CSV and command outputs before using them in production workflows.
✓
Fullscreen mode on tablets and desktops gives more room for waveforms, tables and video previews.
✓
For final broadcast, podcast or advertising delivery, verify results with professional media tools too.
