What this tool does

Convert nearly any text-based subtitle file to the widely supported SRT format.

Handles ASS/SSA, WebVTT, MicroDVD, MPL2, oTranscribe exports, and more.

Format considerations

Advanced styling, positioned text, or karaoke effects from ASS/SSA and WebVTT are flattened into plain SRT cues.

Image-based SUP or SUB/IDX files require the matching pair so OCR can preserve timings.

Conversion tips

Upload up to 50 files at once and download the converted results individually.

Review the timings after conversion, especially when the source used custom frame rates or overlapping cues.
