Add a watermark to video: in your browser
To brand a clip you'd normally upload it to a watermarking site: handing your footage to a stranger's server. Media Razor stamps your text or PNG-logo watermark locally with FFmpeg in your browser instead: private and instant.
Drop your video into Media Razor.
Add your watermark text or upload a PNG logo, then place it.
Download the watermarked video: done.
FAQ
Are my files uploaded to a server?
No. Media Razor runs FFmpeg compiled to WebAssembly inside your browser: no byte of your file ever leaves your device, and there is no server.
Can I use my own logo?
Yes. Upload a transparent PNG logo and Media Razor overlays it on the video locally, or type custom watermark text instead.
Is it really free?
Yes. Every tool is free with no account during the launch: trim, compress, MP3 extraction, 9:16 reframing, watermark and more.
