Frequently Asked Questions

What subtitle formats does the translator support?
The tool supports SRT (.srt) and WebVTT (.vtt) subtitle files encoded in UTF-8. These are the most common subtitle formats used by video players and streaming platforms.
Does the translation preserve timestamps?
Yes. The AI only translates the text content of each subtitle cue. All timestamps (start time, end time) remain exactly as they are in the original file.
What is a bilingual subtitle?
A bilingual subtitle file contains both the original text and the translated text within each cue. This is useful for language learning or audiences who want to follow along in two languages simultaneously.
How many subtitle entries can I translate for free?
You can translate up to 10 subtitle entries without an account. For longer subtitle files, sign in with a free Google account to translate unlimited entries.
Can I edit the translation before downloading?
Yes. After translation, you can double-click any translated cue in the preview to edit it inline before exporting the final SRT file.
