Convert, compress, and extract audio from video files using local WebAssembly. Supports MP4, WebM, MKV, AVI, and MOV.
Is video processing private?
Yes. The video is decoded, edited and re-encoded entirely in your browser with FFmpeg.wasm. Nothing is uploaded to a server and no analytics capture your footage.
Does Smart Remove always look perfect?
No. Smart Remove reconstructs the selected area from the surrounding pixels, so it works best over plain or slowly changing backgrounds. On busy or fast-moving scenes try Blur, Pixelate or Cover for a reliable result.
Can I remove a moving watermark?
This version removes static areas that stay in roughly the same place, such as a corner logo, a timestamp, or a subtitle strip. A region that moves across the frame needs a tracked selection, which is not supported yet.
What happens to the audio?
By default the original audio is preserved and only the picture is edited. You can switch on Remove audio during export if you want a silent video.
