- DownloadPreview the translation and download it as monolingual or bilingual subtitles in the format you want.
Where does the translation happen?
This tool uses your browser's built-in on-device translation interface. In recent desktop versions of Chrome, the language model is downloaded to your computer once; after that, the subtitle text is translated without leaving your device. If your browser doesn't offer this interface, the tool says so clearly; in that case you can translate the subtitles in the Voiser Transcription studio.
Tips for a good subtitle translation
- Because lines are translated one at a time, sentences split across two subtitles are sometimes translated with missing context. For important work, review the result in the subtitle editor.
- If the target language is longer than the source, lines can get crowded on screen; check the reading time.
- Bilingual subtitles are handy for language learning and for checking translations: the translation sits on top, the original below.
Common questions
Which browsers does it work in?
The on-device translation interface is currently available in recent desktop versions of Chrome. In other browsers, the tool tells you and suggests switching to the studio.
Are my subtitles sent to a server?
No. The file is parsed in your browser and translated by the browser's on-device model. Only on first use does the browser download the language pack.
Do the timings change?
No. Every line keeps its exact start and end time; only the text changes.
Which language pairs are supported?
Any pair your browser offers. If the pair you choose isn't available, the tool tells you before the translation starts.
Can this replace professional translation?
It's good for a quick draft. For subtitles going to publication, we recommend having a fluent speaker review them.
