Video Watermark
Add a text watermark overlay to your videos. Customize the text, position (9 positions), font size, and opacity. Perfect for branding, copyright protection, or attribution.
What is it used for?
- Adding branding or logo text to video content
- Copyright protection for original video content
- Adding attribution text to shared videos
- Watermarking preview versions of commercial video
Step-by-Step Guide
- Upload your video file
- Enter watermark text
- Select position from the 9-point grid
- Adjust font size and opacity
- Click 'Convert to .MP4'
- Download the watermarked video
How it works
Upload a video, enter your watermark text, choose position and styling options, then click Convert. FFmpeg's drawtext filter renders the text overlay directly onto the video frames.
Tips & Best Practices
- Bottom-right (BR) is the most common watermark position
- Use 50-70% opacity so the watermark is visible but not distracting
- Font size 24-32px works well for 1080p video
Frequently Asked Questions
Can I add an image watermark?
This tool supports text watermarks only. For image/logo watermarks, use a video editor.
What font is used?
FFmpeg uses its default built-in font. Custom font support is not available in the WASM version.
Privacy & Security
This tool uses FFmpeg compiled to WebAssembly (WASM). The WASM binary (~25MB) is downloaded from a CDN on first use and cached by your browser. All file processing happens locally on your device - your files are never uploaded to any server. This makes it safe for sensitive, private, or confidential media files. Large files may take longer to process depending on your device's CPU and available memory.
