Trim video online: right in your browser
Most online trimmers make you upload your clip first, so your private footage lands on their servers just to cut a few seconds. Media Razor trims locally with FFmpeg in your browser instead: private, frame-accurate, instant, nothing uploaded.
Drop your video into Media Razor.
Set the In/Out points: add more segments if you need.
Download the trimmed clip: 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.
Does trimming keep the audio?
Yes. Media Razor uses output seeking, which is frame-accurate and preserves the original audio track: even for phone and WhatsApp MP4s.
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.
