About Add Watermark
This online tool allows you to add watermarks to videos directly in your browser. Add logos, text, or copyright notices to your videos. Customize position, opacity, and size for perfect branding. Perfect for content creators, businesses, or protecting your videos. All processing happens locally for complete privacy.
What types of watermarks can I add?
You can add image/logo watermarks (PNG, JPG) or text watermarks with custom content. Logos support transparency (PNG recommended).
Can I customize watermark appearance?
Yes! You can adjust position (9 preset positions), opacity (0-100%), size (percentage of video), and margin from edges.
Will adding watermark affect video quality?
The video will be re-encoded with the watermark overlay. Quality impact is minimal when using default settings. The watermark becomes a permanent part of the video.
What file formats are supported?
Video: MP4, WebM, MOV. Logo: PNG (with transparency), JPG, WebP. Output: MP4 or WebM.
Can I preview before downloading?
Yes! After adding the watermark, you can preview the video to verify position and appearance before downloading.
Is my video file safe?
Absolutely! All watermarking happens directly in your browser using FFmpeg.wasm (WebAssembly). Your files are never uploaded to any server. Everything stays private on your device.
How long does processing take?
Processing time depends on video length. Adding a watermark requires re-encoding, typically taking 30-90 seconds for a 5-minute video.
Can I remove the watermark later?
No, watermarks are permanently embedded in the video pixels. Make sure you're satisfied with the preview before downloading. Keep your original unwatermarked video as backup.
