Translate SRT subtitles to Vietnamese with every tone mark
Upload SRT or VTT files and get every line translated into Vietnamese with full tone and vowel marks, on the time codes and numbering of your originals. The first part is translated for free before you sign up for anything. All files in the job, up to 10,000 lines, are $5.
- Vietnamese with full diacritics, saved as UTF-8 with a byte order mark
- Pronouns of address chosen from context: anh, chị, em, ông, bà and more
- Lines never merged, split or reordered
- Bilingual output for learners
- $5 for up to 10,000 lines
Every line, on its timing.
The numbers and time codes of your file are kept exactly; only the words change. Right-to-left languages get the marks players need to show punctuation in the right place.

Tone marks that survive the trip
Vietnamese uses a Latin alphabet with many diacritics: vowel letters such as ă, â, ê, ô, ơ and ư, the letter đ, and tone marks that often sit on top of them, as in ầ or ữ. Lose them and words change meaning. The translation is plain Unicode text, and the file is saved as UTF-8 with a byte order mark, which helps older TVs and media boxes show the marks instead of broken characters.
If you translate from an old Vietnamese subtitle, check that it is Unicode first. Files made with older Vietnamese encodings such as VNI or TCVN3 are read here as Western text and come out garbled; convert them to UTF-8 before uploading.
Pronouns are the hard part
Vietnamese has no neutral words for "you" and "I". Speakers choose pronouns from age, family role and closeness, such as anh, chị, em, cô, chú, ông, bà or con, and the choice can change as a relationship changes during a film. A sentence translated in isolation often gets this wrong. Here each block of up to 60 lines is translated with the lines around it, and the model is told to use them for gender, formality and tone. Read the free first part to see how your characters address each other, and correct pronouns on screen if needed.

Questions and answers
Can ChatGPT translate an SRT file to Vietnamese?
It does well on a short excerpt. On a full-length file, chat assistants tend to stop early, fold lines together or renumber them, and the subtitles drift away from the dialogue.
Is it Northern or Southern Vietnamese?
Standard written Vietnamese, without aiming at Northern or Southern vocabulary. Change regional words on screen before you download.
Can I translate Vietnamese subtitles into English?
Yes. Upload the Vietnamese file and pick English; the tool works out the source language from the text.
How much is a full movie?
You see the first part at no cost. The whole job is $5, once, for up to 30 files and 10,000 lines. Jobs of up to 150 lines in total are free in full.
Can I download a VTT file for a website?
Yes. Choose VTT when you download; SRT is available too, whichever format you uploaded.
What happens to my files?
Only you can see them. They go to an AI model provider for translation, are not used for training, and you can delete the job at any time.
