Translate SRT subtitles without breaking timing or tags

SRT is the most common subtitle format on the web, and translating one usually means re-timing everything by hand. Generic tools smash / inline tags and flatten cue line breaks, so your subtitles come back broken. LocaFile AI is a subtitle translation tool that locks inline tags and preserves cue timing byte-safe before the AI sees a single word.

Upload your .srt, pick your target languages, and download translated subtitles that drop straight back into your video player or game cutscene. One file, one pass, from $19 — no login, no subscription.

SRT translation for game cutscenes and video

Game cutscenes and trailers use SRT as the hand-off format, and subtitles carry the same risk as game strings: a {player_name} in a subtitle line is a variable, not prose. Our variable-safe, engine-aware pipeline treats subtitle cues with the same protection as Godot or Unity files.

Whether you are localizing cutscene dialogue for Steam or subtitling a devlog for YouTube, you get consistent character names, preserved timing, and clean SRT output in 28+ languages.

Why not just use YouTube or TikTok auto-translate?

YouTube, TikTok and streaming platforms translate captions inside their players — useful for viewers, useless for you: the translated captions can't be exported as a file, never leave the platform, and never become part of your own distribution. Festival submissions, e-learning courses, second channels, and offline video all need actual subtitle files.

That is the gap this tool fills: file in, file out, timing and tags byte-safe. Output is AI-translated — label it as such on the video. One file, one pass, from $19, no login, no subscription.

Translate SRT subtitles — FAQ

Will translating an SRT file keep my cue timing?

Yes. Every timestamp is preserved byte-safe through the normalized cue model — the sync stays exactly as it was, so subtitles still match the audio. From $19 per file, no login required.

Are / inline tags safe to translate?

Yes. Inline tags are locked with token replacement before the AI sees your text and restored byte-for-byte after, so emphasis and formatting survive translation.

Do you handle SDH / hearing-impaired subtitles?

Yes. SDH content like [door creaks] or (music playing) is handled as caption content and translated naturally, while brackets and structure stay intact.

Why not just use YouTube or TikTok auto-translate?

Platform auto-translate works only inside that platform's player and can't be exported as a file. If you need translated subtitles off-platform — festival submissions, e-learning, your own channels, offline video — you need a subtitle file with timing intact. That's exactly what this service produces (AI-translated; label it as such).

How is pricing calculated for an SRT file?

One subtitle file = one pass, from $19 flat. Word count is shown upfront before you pay — no per-word surprise billing, no hidden fees.

Do I need to create an account, and can I translate to several languages at once?

No login required — upload, pay, download. You can translate one SRT into multiple target languages in a single pass across 28+ languages.
