- 50+ Language SupportTranslate subtitles into 50+ languages including English, Spanish, French, German, Chinese, Japanese, and Korean. Reach a global audience effortlessly.
- Multiple Subtitle FormatsUpload SRT, VTT, SBV, SUB, ASS, LRC, or SMI files. No manual format conversion needed. Translated output is in SRT format, and you can use the Subtitle Converter for other formats.
- Batch ProcessingUpload up to 5 subtitle files at once and translate them into one target language. Or translate a single file into up to 10 languages simultaneously. Smart queue management keeps batch processing fast and efficient.
- Simple Pricing PlansChoose from a one-time Credits Pack ($12 for 200 credits), Pro ($10/month for 200 credits/month), or Pro+ ($18/month for 400 credits/month). No hidden fees, cancel anytime. New users get a small amount of free credits upon registration.
- Free Basic Model LimitationsThe Basic (Free) model uses Basic translation quality and does not deduct credits, but 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 limited by per-user daily limits, maximum estimated credit cost per subtitle, and a shared daily free credit pool.
- Output Format and Style LossThe 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, use the Subtitle Converter to convert the translated SRT files.
- No Strict Word Limit but Potential FailuresThere is no strict word limit on translations, but for extremely long subtitle files, the translation might fail due to processing time limits of the AI models.
- Data Retention and Subscription CreditsUploaded and translated subtitles are saved for 7 days. Unused subscription credits do not carry over to the next billing period. Refunds are available within 7 days of purchase, with partial refunds based on unused credits; no refunds after 7 days or once all credits are used.

Choose DeepL if: You prioritize maximum translation quality for general text and documents, and you are willing to convert subtitle files to a compatible format first.

Choose AI Subtitle Translator if: You want a streamlined workflow for translating subtitle files directly, with support for multiple formats and batch processing.
