Convert TS to MKV — Free Online Converter

MPEG Transport Stream and Matroska (MKV) are both container formats capable of holding multiple audio, video, and subtitle streams. However, TS is designed for broadcast transmission with 188-byte packet overhead and error correction, while MKV is designed for file-based storage with efficient variable-size EBML framing, chapter support, and virtually unlimited codec flexibility.

MKV supports everything TS offers — multiple audio tracks, subtitles, metadata — but in a more efficient file-based container without broadcast overhead. MKV files are typically 2-5% smaller than equivalent TS files due to the removal of null packets, PAT/PMT tables, and fixed packet padding. MKV also adds chapter markers, attachments (fonts, thumbnails), and seamless codec switching that TS lacks.
