About SUB/IDX to SRT conversion

SUB/IDX (VobSub) subtitles use images instead of text. This tool runs OCR to extract text and rebuilds a standard SRT file.

No IDX file?

If you only have a .sub file, this tool will not work. You can try the Convert to SRT tool in case it is actually a MicroDVD text subtitle.

Multiple languages

VobSub can contain multiple languages. We will process every language; you can download them individually or as a ZIP on the results page.
