Trimming AVI without touching the quality
Flippy trims AVI 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 AVI container makes the cut with it, soundtrack included.

Questions people ask
Does trimming an AVI re-encode it?
No: Flippy uses stream copy, so the trimmed AVI keeps the exact original quality and the cut takes seconds, not minutes.
Will I lose quality working with AVI here?
None. Stream copy moves your AVI's data untouched; only the length changes.
Is this AVI 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.
