Trimming MP4 without touching the quality
Flippy trims MP4 with stream copy: it slices at the nearest safe boundary and copies the data straight across: no re-encoding, no quality loss, and it's near-instant even on big files. Everything travelling inside the MP4 container makes the cut with it, soundtrack included.

Questions people ask
Does trimming an MP4 re-encode it?
No: Flippy uses stream copy, so the trimmed MP4 keeps the exact original quality and the cut takes seconds, not minutes.
Will I lose quality working with MP4 here?
None. Stream copy moves your MP4's data untouched; only the length changes.
Is this MP4 trimmer really free?
Yes: free for everyday use with no daily cap, no signup, and your files delete themselves from our servers within an hour. Pro exists for heavy days: bigger files, whole folders at once.
