How to translate English subtitles to Thai

01

Upload

Drop in your English .srt or .vtt file. SubLingo parses every cue and locks the timings in place.

02

Pick Thai

Set the target language to Thai. The source is auto-detected, so you can leave it on English or let it detect.

03

Translate

Run the translation. Only the text inside each cue is rewritten in Thai — never the timecodes.

04

Download

Download the Thai subtitle file in the same format you uploaded, ready to drop straight onto your video.

Thai subtitle considerations

Translating from English into Thai: Thai is written without spaces between words, so line breaking relies on dictionary-based segmentation; keep cue text short so players wrap it cleanly. Because only the text inside each cue changes, every timecode from the original English file carries over unchanged.

EnglishThai questions

Will the timecodes change when translating English to Thai?+

No. SubLingo translates only the subtitle text, so every start and end time is preserved exactly. Your Thai subtitles stay frame-accurate against the original video.

Does it support .vtt files as well as .srt?+

Yes. Both WebVTT (.vtt) and SubRip (.srt) English files are supported, including multi-line cues. The output keeps the same format you uploaded.

Can I translate English to Thai for free online?+

Yes. You can translate a English subtitle file to Thai in your browser for free, with no signup and nothing to install.

Is the English to Thai translation really free?+

You can try it for free with no account. Upload your English file, translate to Thai, and download the result.

How long does it take to translate English subtitles to Thai?+

Most English subtitle files translate to Thai in a few seconds. Longer files with thousands of cues take a little more, but you stay on the page the whole time.

Is there a file size or length limit for Thai subtitles?+

Typical movie and episode subtitle files — a few hundred KB and a few thousand cues — translate without trouble. Very large files may take longer to process, but the timecodes still come back unchanged.
