Resolution + bitrate
Pick exact targets when the presets don't fit your need.
The desktop transcoder is fantastic — but it's an eighty-megabyte install that doesn't run on iPad or Chromebook. The online converters cap free files and queue you behind everyone else, limit free uploads to ten megabytes, or watermark past ten minutes. Flowcut runs the same FFmpeg encoder those tools use under the hood — H.264, H.265, VP9, adjustable CRF, two-pass — compiled to WebAssembly and running in your browser tab. Discord 25MB, email 10MB, YouTube optimal, Instagram — pick a preset, hit go.
The same FFmpeg encoders professional editors run, compiled to WebAssembly. Typical reductions are 40-70% for 1080p footage when dropping to 720p or trimming bitrate. A 2GB raw screen recording usually lands under 200MB without visible quality loss.
Discord 25MB, email 10MB, YouTube optimal, Instagram — each preset is tuned for max quality at its ceiling.

Brand-new compressed file. Source video sits where you dropped it from.
The desktop transcoder is technically the right answer — but it's an eighty-megabyte download that updates quarterly and doesn't run on iPad or Chromebook. The online converters stick free users in a render queue and run banner ads on the result page, cap free uploads at ten megabytes or one gigabyte, or watermark the export past ten minutes. The pattern is upload → queue → cap → paywall. Flowcut runs the same FFmpeg encoder the desktop transcoder uses, but compiled to WebAssembly so it runs in your browser tab. No install. No queue. No cap. No watermark. The compressed file lands on your disk.
Typical 40-70% reduction for 1080p footage. A 2GB screen recording usually lands under 200MB.
Yes — the actual FFmpeg encoder compiled to WebAssembly. Adjustable CRF, two-pass encoding, the full toolchain.
No server cap. Bounded only by your device's RAM. 4K wedding videos and hour-long screencasts compress locally.
Yes. Safari on iOS supports SharedArrayBuffer with COOP/COEP headers Morph sets. Encoding runs locally.
Untouched. The compressed version is a brand-new file. Morph never modifies source files.
