Online AI Subtitle Translator

AI Subtitle Translator is an advanced tool that uses artificial intelligence to translate subtitles from one language to another. It supports a wide array of languages and multiple subtitle formats, making it a comprehensive solution for translating subtitles for global audiences.

The AI Subtitle Translator supports numerous languages, including but not limited to English, Spanish, French, German, Chinese, Japanese, and Korean. For a full list of supported languages, please refer to the language support section on our website.

Currently, our AI Subtitle Translator supports multiple subtitle formats, including srt, vtt, sbv, sub, ass, lrc, and smi. We are continuously working to support more formats to ensure broad compatibility.

The translated output is currently in SRT format regardless of the input format, which means style information from formats like ASS may not be preserved. If you need a different format, you can use our Subtitle Converter to convert the translated SRT files into VTT, ASS, or other formats.

We currently do not impose a strict word limit on translations, aiming to provide you with a more flexible service experience. However, please note that for extremely long subtitle files, the translation might fail due to processing time limits of the AI models.

To use the AI Subtitle Translator, simply upload your subtitle file, select the target language, and click the translate button. There's no need to select the original language as our system will automatically detect it.

If the language you need for translation is not currently supported, please contact us via email. We will consider adding it to our list of supported languages.

AI Subtitle Translator offers new users a small amount of free credits upon registration to try our service. For continued use and additional credits, users can subscribe to our service plans or purchase credit packs. This helps us maintain high-quality translation services while keeping them accessible to everyone.

Basic (Free) uses Basic translation quality and does not deduct credits. It runs in a separate slow queue, processes one free task at a time, and only supports one subtitle file with one target language per submission. Free use is also limited by the per-user daily limit, the maximum estimated credit cost per subtitle, and the shared daily free credit pool. When the pool is used up, please come back after the next daily reset.

The uploaded subtitles and translated subtitles will be saved for 7 days. Please download them as soon as possible. You can also view them in the 'My Subtitles' page.

Yes, you can translate multiple subtitle files at once. You can upload up to 5 subtitle files at a time. The target language for all files will be the same.

The Basic model offers standard translation quality with faster processing speed and lower cost. The Plus model uses more advanced AI to provide higher translation quality, but it requires more processing time and costs more credits.

The credit multipliers are not fixed. We may adjust the multipliers based on operational costs to provide a sustainable and high-quality service.
