Questions
Is it free?
Yes. There is no sign-up and no watermark on the subtitle files.
Is my video uploaded?
Your video itself never leaves your device. In Best quality mode, only the sound is sent to our server in short pieces, turned into text by our AI, and not stored. In Private mode nothing is sent at all: the AI runs in your browser (it downloads 77 to 250 MB once).
Why is there a 30-minute limit?
Everything runs on your own device, and longer files can make a browser run out of memory. For files up to 8 hours, use the Subtitle Converter Android app.
How long does it take?
Best quality usually finishes a 30-minute file in a few minutes. Private mode depends on your computer: on a typical laptop it takes about as long as the file, or about three times as long for Urdu, Arabic and other languages. The tool shows an estimate before it starts.
Which languages can I translate into?
In Best quality mode you can translate between any of the 31 languages, for example Urdu to English or English to Arabic. In Private mode, languages other than English need the translator built into a recent Chrome on a computer.
How accurate are the subtitles?
In our tests Best quality got about 98% of words right in Urdu, Arabic and English. Real recordings with music, noise or several people talking at once score lower, so you can edit every line before downloading. Make sure the spoken language is set correctly.
