Are these subtitle and video tools really free?

Yes. Every tool on this page is free, adds no watermark, and needs no account. The subtitle tools have no limits or file size cap; the video tools have fair daily limits and accept uploads up to 500MB on the free tier.

Do the subtitle converters upload my files to a server?

No. The subtitle converters, fixers, and validators run entirely in your browser using JavaScript. Your subtitle files are processed locally and never leave your device.

Which subtitle formats can I convert between?

You can convert between SRT (SubRip), VTT (WebVTT), ASS (Advanced SubStation Alpha), SBV (YouTube), and plain text. Each direction has its own dedicated converter listed on this page.
