Why Convert MTS to MP3

Plays on Every Device

MP3 is universally supported by every phone, computer, car stereo, smart speaker, and portable player manufactured in the last 25 years. No other audio format comes close to MP3's device compatibility.

Smallest Music Files

MP3 at 128-320 kbps delivers excellent music quality at a fraction of the size of uncompressed audio. A typical 4-minute song is just 3-10 MB, making large music libraries manageable.

Universal Car Stereo Support

Every car stereo with a USB port, Bluetooth connection, or CD-MP3 capability plays MP3 files. USB drives loaded with MP3 files work in every vehicle from economy cars to luxury automobiles.

ID3 Metadata Tags

MP3 supports comprehensive ID3 tags for artist, album, track number, genre, album art, and lyrics. Music players and library managers use these tags to organize and display your music collection.

Podcast and Audiobook Standard

Virtually every podcast directory and audiobook platform distributes content as MP3. RSS feeds, podcast apps, and audiobook players are all optimized for MP3 playback and download management.

About the MTS Format

MTS (MPEG Transport Stream) is an AVCHD video file format jointly developed by Sony and Panasonic. It uses the MPEG-2 transport stream container to store H.264/AVC high-definition video along with Dolby Digital or PCM audio. MTS files are the native recording format for many HD camcorders from Sony, Panasonic, Canon, and other manufacturers.

MTS files deliver broadcast-quality HD video at 1080i or 1080p resolution. However, the AVCHD format has limited software compatibility compared to MP4 — many video editors and media players require conversion before the footage can be used. Converting MTS to MP4 preserves the HD quality while making the video universally playable across devices and platforms.
