Because M2TS supports H.264 just like FLV does, the video stream can be carried across without a quality-costing re-encode.
At 1080p, FLV typically runs around 4.5 Mbps while M2TS sits near 28 Mbps, which is the main driver of the size difference you will see.
This is an older container, introduced in 2006, and browsers will not play it directly. It is best suited to archival or a dedicated player.
This page converts FLV video, stored in the Flash Video container since 2002, into M2TS, which uses BDAV MPEG-2 Transport Stream and dates from 2006. The codecs each container accepts decide whether the picture has to be re-encoded.
FLV comes from Adobe (Macromedia) and dates to 2002. It usually holds H.264, Sorenson Spark, or VP6 video with AAC or MP3 sound, and those streams set the ceiling for anything converted out of it.
M2TS comes from Blu-ray Disc Association and dates to 2006. It holds H.264, MPEG-2, or VC-1 video alongside AC-3, DTS, or LPCM audio, and every major platform needs a media player such as VLC to open it.
