How It Works

How to use the multilingual subtitle generator

01

Upload your file

Drop the audio or video you want translated.

02

Transcribe and translate

The speech is transcribed with timings, then every line is translated into English, keeping the timings.

03

Download subtitles

Download the SRT or VTT, or copy the text — the original-language file comes with it.

What is the multilingual subtitle generator?

The Multilingual Subtitle Generator is a free online tool from ShortsHero: one upload, subtitles in 10+ languages. The speech is transcribed by AssemblyAI, then every line is translated with its timings kept — usually under a minute for a 5-minute file. It is free for files up to 1 hour; longer recordings need a paid plan.

Free transcription covers files up to 1 hour. If your recording is longer, a paid plan lifts the limit — or trim it into parts and run each one.

FAQ

Common questions

Still stuck? Email us.

Is this multilingual subtitles free?

Yes. Files up to 1 hour long are free, with no watermark and no account needed. Recordings longer than 1 hour need a paid ShortsHero plan.

Which files can I upload?

MP4, MOV, WebM, MKV, MP3, WAV, M4A, AAC, OGG, FLAC and most other audio and video formats, up to 1 GB. For a long video, uploading just the audio is faster.

Do the translated subtitles keep the original timing?

Yes. The speech is transcribed into timed lines first, and each line is translated on its own, so the English subtitles appear exactly when the words are spoken.

How long does it take?

Usually well under the length of the recording — a 10-minute file is typically done in about a minute.

What else can ShortsHero do?

ShortsHero turns long videos into short vertical clips with AI moment detection, face tracking and animated captions — and has free tools for subtitles, transcripts and video formats.

Got a long video? Make it Shorts.

The same transcription powers ShortsHero's clip maker: it finds the strongest moments, reframes them to vertical and adds word-by-word captions in 36 styles.
