What's in the Watermark Studio?
The Watermark Studio is our full-featured video branding environment. Unlike simple watermark overlays, the Studio gives you fine-grained control over every aspect of your watermark—motion, timing, opacity, positioning, and style—all processed locally in your browser using WebAssembly.

How to Use the Watermark Studio
Load your video
Drag and drop or click to select an MP4, WebM, or MOV file. The Studio loads a preview instantly—no upload required.
Choose a watermark style
Select from 6 preset styles. Upload your PNG logo or type a text watermark (like your @handle or website). Adjust size and opacity to taste.
Preview and export
Watch a live preview of your watermark before committing. When ready, click Export — FFmpeg renders the final MP4 directly in your browser. Download when done.
Available Watermark Styles
Each style is designed for a different use case. Choose based on your platform and brand identity:
Elegant Corner
Classic static placement in any corner. The most professional and universally used style. Best for YouTube long-form and business content.
Glass Ribbon
A translucent bar spanning the video frame. Gives a broadcast-television feel. Ideal for news, product demos, and corporate videos.
Ghost Float
Animates subtly across the frame. Nearly impossible to crop or remove cleanly. Great for content you want to protect from re-uploaders.
News Ticker
Scrolling text along the bottom. Use it to display your @username, website URL, or any continuous text branding.
Privacy-First: Your Files Never Leave Your Device
Unlike cloud-based video editors, the Watermark Studio runs entirely in your browser using WebAssembly (WASM) — a technology that compiles native-speed code to run inside a web page. We compile FFmpeg to WASM, so professional video processing happens locally on your hardware.
- ✓ No server upload — your video bytes never leave your machine
- ✓ No account or login required — open the page and start watermarking
- ✓ Works offline after first load — safe for confidential client footage
- ✓ No watermark from us — the only branding in your output is yours
Frequently Asked Questions
What's the difference between the Studio and the other tool pages?
The Studio is the most advanced interface with all 6 watermark styles, full preview controls, and the complete feature set. The platform-specific pages (YouTube, Instagram) offer simplified workflows tuned for those platforms.
What video formats does the Studio support?
Input: MP4, WebM, MOV. Output is always a high-quality MP4, which is universally compatible with YouTube, Instagram, TikTok, and all major platforms.
Is there a file size limit?
There's no strict size cap — the limit is your device's available RAM. Most modern devices can handle files up to several gigabytes. Processing time scales with file size and your hardware.
Will the watermark reduce video quality?
The watermark itself doesn't degrade quality. The export re-encodes the video using FFmpeg's default high-quality settings. For best results, start with the highest quality source file you have.
Can I use this for client work or commercial projects?
Yes. You retain full rights to your output. Use it for client deliverables, commercial campaigns, branded content — whatever you need.
