FLV Video Compressor
FLV (Flash Video) was the dominant web video format from 2005 to 2015, used by early YouTube, Newgrounds, and countless Flash-based websites. With Flash Player's discontinuation in 2020, FLV files cannot play in any modern browser or device without conversion. CompressYourVideo.com converts FLV to compressed MP4, making your old Flash videos playable again on every device. This is essential for anyone with archives of old web video downloads, Flash game recordings, or early YouTube saves. The conversion typically reduces file size while dramatically improving compatibility, since modern H.264 encoding is far more efficient than the codecs used in FLV files from the 2000s.
