What compressing FLV actually does
Compressing FLV means re-encoding the video inside with a modern codec at a quality you choose: low, medium or high. Camera footage typically gives up 30–70% of its size before quality visibly suffers, and screen recordings squeeze even harder. FLV runs small files with dial-up-era expectations about quality, so there's usually plenty to give.
Questions people ask
How much smaller will my FLV get?
It depends on how generously it was encoded: FLV typically runs small files with dial-up-era expectations about quality, and most files give up 30–70% at the medium preset before quality visibly suffers.
Will I lose quality working with FLV here?
Where possible Flippy copies streams without re-encoding; when a re-encode is unavoidable it happens once, at quality matched to your FLV.
Is this FLV compressor 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.
