Video Watermark Remover
Upload a video and seamlessly paint over watermarks, logos, or objects to erase them. Processing runs natively in your browser.
Flawless Video Watermark Removal
Leverage advanced OpenCV inpainting and client-side demuxing to scrub logos, timestamps, and watermarks from your videos frame-by-frame, without ever leaving your browser.
OpenCV Inpainting
Utilizes the powerful INPAINT_TELEA algorithm natively ported to WebAssembly. The engine automatically analyzes neighboring pixels to realistically fill the masked area frame by frame.
Client-Side Processing
Uses the HTML5 WebCodecs API to demux, decode, and remux MP4 files directly in your RAM. Enjoy zero upload waiting times and instantaneous processing starts.
100% Local Privacy
Your videos are never transmitted to a cloud server. Because the entire pipeline executes within your local environment, absolute data privacy is guaranteed.
Precision Masking
A custom dynamic canvas layer allows you to scrub the timeline and paint the exact boundaries of the watermark with a non-destructive brush, ensuring high-fidelity outputs.
System Requirements & Compatibility
Video decoding and WebAssembly execution are CPU-intensive operations. Please ensure your device meets the minimum hardware specifications.
Hardware Specs
- Memory (RAM)Minimum 4GB required. WebCodecs stores massive frame arrays in memory during the demuxing phase.
- ProcessorMulti-core desktop CPU highly recommended. Frame-by-frame OpenCV analysis will drain laptop batteries quickly.
