About subtitle formats
- Choose SRT, ASS, VTT, SBV, or MicroDVD (SUB) text files, or SUP and paired SUB/IDX image files.
- Select an output format. For image subtitles, confirm the subtitle language before starting OCR.
- Convert locally, then download each result. Image subtitle results can also be reviewed and edited.
What is the difference between text and image subtitles?
SRT, ASS, VTT, SBV, and MicroDVD (SUB) contain text and timestamps or frame numbers. PGS (SUP) and VobSub (SUB/IDX) contain pictures of text, so converting them to text requires optical character recognition (OCR). Text and image files are converted in separate batches.
Do my subtitle files leave my device?
No. Subtitle processing happens in your browser. OCR models may be downloaded, but your subtitle files are not sent to our server. Keep the tab open while converting.
