What People Use It For

A subtitle file that has to change format, in a batch, with the text untouched: the player that refuses one container, the web page that needs another, the translator who wants a table, and the transcript that only needs the words.

The player will not show the subtitles

A TV, player or editing tool that will not accept the subtitle format you have.

The web player needs VTT, not SRT

Convert a folder of SRT files to WebVTT for HTML5 video - names kept.

Translate the subtitles in a spreadsheet

SRT to CSV with id, start, end and text - edit the text, then convert back to SRT.

Just the words, without the timestamps

Turn subtitles into a plain-text transcript, with or without simplified timings.

The subtitles must not leave the machine

Unreleased video, client work, material under NDA: batch-convert subtitle formats on your own computer, with nothing uploaded to an online converter.

Frequently Asked Questions

What subtitle formats does SubtitleConverter support?

SubtitleConverter supports 15+ subtitle formats, including SRT, VTT, ASS/SSA, XML/TTML, DFXP, SMI, MicroDVD (.sub), SubViewer2.0, YouTube (.sbv) and LRC. It is specialized in SRT to CSV/TXT conversion for easy subtitle data processing.

How many subtitle files can I convert at once?

There is no strict quantity limit. SubtitleConverter supports recursive folder scanning and can batch convert 1000+ subtitle files in a single run.

Does it translate the subtitles?

No. SubtitleConverter converts between subtitle formats; it does not machine-translate. If a subtitle has to be translated, convert it to CSV, let a translator or a translation tool work on the text column, then convert the CSV back to SRT/VTT - the timings are preserved either way.

Are my subtitle files uploaded anywhere?

No. Everything runs on your own computer. Subtitles often cover unreleased or client material, so nothing is sent to an online converter or a cloud service.

What is included with purchase?

All purchases include full license to use the software, free minor upgrades and free technical support by e-mail.
