How to Watermark Videos Online
Protect your video content the same way you protect your photos. Upload your video, add a text or logo watermark, and download the result — all from your browser, no editing software required.
Video content is even easier to steal than photos — a single download or screen recording and your work is someone else's. Watermarking your videos adds a persistent visual layer of ownership that travels with the file no matter where it ends up. Watermark.ws processes videos directly in your browser so you can add your watermark and download the result without installing any video editing software.
Upload MP4, MOV, AVI, and other common video formats. Watermark.ws processes them directly in your browser and exports a watermarked version ready to share or upload anywhere.
Your watermark appears on every frame of the video from start to finish. Whether someone watches the first second or the last, your ownership mark is always visible.
Place your watermark in any corner, along the bottom, or centered across the frame. Adjust the size and opacity so it protects your content without distracting from the viewing experience.

Frequently Asked Questions
What video formats can I watermark?
Watermark.ws supports MP4, MOV, AVI, and other common video formats. MP4 is the most widely used and recommended format for best compatibility when sharing online.
Will the watermark appear on the entire video?
Yes. The watermark is applied to every frame of the video, so it is visible from the first second to the last. There is no way for someone to skip past it or crop it out of a single frame.
Does watermarking reduce my video quality?
Watermark.ws preserves the quality of your original video as much as possible during processing. The watermark is added as an overlay without re-encoding at a lower bitrate, keeping your video looking sharp.
Can I watermark multiple videos at once?
Yes. You can upload and watermark multiple video files in a single session. Apply the same watermark across all of them and download each one when processing is complete.
