Video Watermark
Add text or image watermarks to videos online. Customize position, opacity, size, rotation and color. No installation required.
How do I add a watermark to my video?
Upload your video, choose text or image watermark type, customize the settings (position, opacity, size, rotation, color), then click Add Watermark to process.
Can I use my logo as a watermark?
Yes! Upload a PNG image with transparency as an image watermark. It will be overlaid on your video at your chosen position and opacity.
Is my video uploaded to a server?
No. All processing happens locally in your browser using FFmpeg WASM. Your videos never leave your device, ensuring complete privacy.
What video formats are supported?
This tool supports MP4, WebM, MOV, and AVI video formats. The output can be saved as MP4 or WebM.
Can I adjust the watermark position?
Yes, you can drag the watermark to any position on the video or use preset positions like corners and center.
How do I make the watermark less visible?
Reduce the opacity slider to make the watermark more transparent. You can also adjust the size to make it smaller.
Can I add multiple watermarks?
Currently, the tool supports adding one watermark at a time. You can process the video multiple times if needed.
Is this tool free to use?
Yes, this tool is completely free with no limitations. All processing happens in your browser, so there are no server costs.
Can I customize the text font?
Yes, you can choose from various font families, adjust font size, color, and add text styling options.
Does the watermark affect video quality?
No, the watermark is added without reducing video quality. The output maintains the original video resolution and quality.
Can I remove the watermark later?
Once added, the watermark becomes part of the video. We recommend keeping the original video file if you might want to remove it later.
What is FFmpeg WASM?
FFmpeg WASM is a WebAssembly port of FFmpeg that runs directly in your browser, enabling video processing without server uploads.
How to Use Video Watermark
Overlay a text or image watermark on your video and control its position, size, opacity, rotation, and colour. Rendering happens entirely in your browser — the file never leaves your device.
- Load the video you want to protect.
- Choose a text watermark or an image logo, and set the text colour if needed.
- Position the watermark and adjust its size, rotation, and opacity in the preview.
- Select MP4 or WebM as the output format.
- Pick High, Medium, or Low quality — High preserves detail but renders slower and produces bigger files.
- Render the video and download the watermarked result.
An opacity around 50% marks ownership clearly without pulling attention away from the content.
