Add Text or Image Watermarks Without Installing Software
A browser-based editor for fast branding, creator attribution, and private local processing.
Add brand names, handles, copyright notices, captions, or creator credits with adjustable size, color, opacity, and placement.
Upload a PNG, JPG, or WebP logo and position it with precise corner, center, margin, and scale controls.

FFmpeg.wasm processes your source video and watermark locally, so files do not need to be uploaded to a server.
How It Works
Watermark a Video in Three Steps
Upload a video, position your watermark, and download the MP4. No login is required.
Upload Your Video
Choose an MP4, MOV, WEBM, MKV, or AVI file up to 100MB. The tool reads it locally and creates a cover preview.
Customize the Watermark
Choose text or image mode, then adjust position, opacity, margin, width, text size, color, and background.
Export a Watermarked MP4
Render the result in your browser and download a clean MP4 with the watermark permanently added.
Use Cases
Protect and Brand Videos Before Sharing
Use the free tool for social clips, previews, demos, lessons, and client-facing drafts.
Place your logo or brand name on TikTok, Instagram Reels, YouTube Shorts, Facebook, and LinkedIn clips.
Add a handle, website URL, copyright label, or ownership mark before sharing previews with clients or collaborators.
Watermark tutorials, product demos, screen recordings, and training clips so shared drafts remain attributed.
Watermark Tips
Make Your Watermark Visible Without Distracting Viewers
A few practical settings make watermarks clearer, cleaner, and easier to read.
Bottom-right and top-right keep logos visible without covering the main subject.
An opacity between 60% and 90% is usually readable while remaining professional on busy backgrounds.
Transparent PNG files avoid visible rectangular edges and usually produce the cleanest result.
Check placement, size, and contrast in the cover preview before rendering the final MP4.
