💡Pro Tips: Watermarking Best Practices
- •Bottom-right corner at 70% opacity is the industry standard for watermarks
- •Use white text with a semi-transparent dark box for text watermarks on any background
- •PNG logos with transparency look much cleaner than JPG logos
- •Keep watermarks subtle — aggressive watermarks annoy viewers
- •Add copyright year: "© 2026 YourName" for professional branding
How the Add Watermark to Video works
The watermark is burned into the video with FFmpeg (WebAssembly) in your browser. A text watermark (default “© 2026 YourName”, 24 px, white, 70% opacity) or a logo image is placed in a corner, the centre or a custom position you drag on the preview.
Logos are blended with FFmpeg’s overlay filter after applying your opacity through colorchannelmixer, and the video is re-encoded with H.264 (preset ultrafast, CRF 23).
Example: branding a 1080p clip
For a 1920 × 1080 video, a 150 px wide PNG logo in the bottom-right corner at 60–70% opacity is clearly visible without distracting from the content. Use a transparent PNG so only the logo, not its background box, appears.
Tips for the best result
- Use a PNG with transparency for logos.
- Bottom-right is least likely to cover faces or subtitles; avoid the bottom centre if the video has captions.
- Scale the watermark to the video: about 8–10% of the frame width works well.
Limitations to know
- Burned-in watermarks are permanent; keep an un-watermarked master copy.
- Re-encoding takes time and long 4K videos can exceed browser memory.
Troubleshooting
- Logo has a white box around it
- The logo is a JPG or a PNG without transparency. Export it as a transparent PNG.
- Processing stays at 0%
- The FFmpeg engine (about 30 MB) is downloading on first use; wait or check your connection.
Add Watermark to Video: common questions
Can I use my own logo?
Yes. Choose the image watermark type and upload a PNG, ideally with a transparent background.
Can the watermark be removed later?
Not easily: it is burned into the video frames, which is what protects your content.
What output format do I get?
An MP4 encoded with H.264.
Are my videos uploaded?
No, FFmpeg runs entirely in your browser.
