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 — trim, compress, MP3 extraction, 9:16 reframing, watermark and more — is free with no account during the launch.
