Buyer's guide
How to choose a subtitle translator
If you just need a subtitle translated once or twice and want to avoid signing up or pasting API keys, AllSubConverter works directly in your browser with a fixed set of 19 languages. If you are localizing a whole series, need more than 19 languages, or want to keep the original text visible alongside the translation for learning or fan‑sub purposes, GeekLink offers batch processing and bilingual export, though you’ll need to install the app and may hit a trial limit.
