English to Thai subtitle translator.

Upload a English subtitle file and get a Thai version with identical timecodes. The translation reads the surrounding cues, so split sentences and pronouns come out right, and it follows subtitle line-length rules for Thai.

First file free (up to 150 cues). 1 credit = 1 file × 1 language.

Thai has no spaces between words, so line breaks must fall at word boundaries — we break at natural phrase points and keep the polite particles consistent.

About English sources

English subtitles are the gateway to the widest audience and to YouTube search in English. We keep lines under 42 characters and split at phrase boundaries so they never overflow.

Register and glossary

Pick formal or casual once and it is applied to the whole file. Add names and terms to the glossary so they are spelled the same in every Thai cue.

Formats

SRT, VTT, SBV, ASS/SSA and SMI are supported; you download the same format you uploaded.

Questions

Will the Thai subtitles fit on screen?
Lines are kept under about 42 characters (20 for CJK) and split at phrase boundaries, so they fit standard players.
Is the first file free?
Yes, one file per day up to 150 cues with no account. Larger files use credits: 10 for $4.99.
Do you upload my file?
No. The file is parsed in your browser; only the text is sent to the translation model and is not stored.
