Free video editor that snaps cuts to the beat.
Cutflux runs in your browser. Drop a clip, drop a song, hit "snap to beat", your edit is locked to the music in seconds. No signup. No watermark. No install.
Why Cutflux instead of CapCut, Clipchamp, or Veed?
Auto beat-sync
A dynamic-programming beat tracker locks every cut to a real onset. Most free editors only let you snap to manual markers.
No login required
The full editor opens without an account. Most browser editors paywall this behind a Microsoft, Google, or email signup.
No watermark
1080p exports are clean. No corner logo, no preroll, no upsell modal at export time.
Stays in your browser
Audio analysis and trimming run client-side. Your footage never has to leave your machine.
Free to use, not a trial
Not "free for 7 days then $20/mo". Free is the actual tier.
Built for short-form
1080×1920 exports, beat-locked cuts, captions, and smart reframe, the toolset short-form creators actually need.
