Your .smi file won't open in modern players?

Legacy .smi (SAMI) files from old Windows Media content or Korean movie releases often won't open in modern video players. Converting SMI to SRT reads each <SYNC Start="ms"> block and produces a plain SubRip subtitle — the most widely supported format around — so your captions work in every player and editor.

The conversion runs 100% client-side — your file never leaves your device.
