Second language
Shows a translation under the captions – great for language learners and international audiences.
Translate the captions into another language. The timing stays, and you can correct every line.
Each translation becomes its own language. Switch between them under Captions, export each one, or show two at once under Style.
Video with captions (MP4)
The captions are burned into the picture, exactly as in the preview – for TikTok, Reels, Shorts, WhatsApp and every player.
This browser cannot create videos. Use a current Chrome, Edge or Safari – the subtitle files below work everywhere.
Subtitle files
For YouTube, Vimeo and editing programs: upload the file next to your video. ASS keeps your look; LRC is for song lyrics.
Project
Saves captions, translations and look as a small file. Open it later together with the same video to continue.
Your video stays with you. Recognition, translation and the MP4 are all made on your device. Only the AI models are downloaded once.
No watermark, no minute limit. Export as many videos as you like, in Full HD or up to 4K.
How to translate subtitles
Drop your video or SRT
Choose the video, or first an existing SRT or VTT file and then the video. Pick the language to translate into.
Translate
The captions are translated sentence by sentence, so the meaning carries over, and every caption keeps its timing. Correct any line.
Export the translation
Save the translated SRT for YouTube, or burn it into the video – alone or under the original as dual subtitles.
Everything a subtitle editor needs
- Word-accurate timing – every word has its own time, so captions highlight the spoken word like karaoke.
- Seven looks, fully adjustable – font, size, colours, outline, glow, background box, position, animation.
- Timeline editing – drag captions, stretch their edges, split, merge, find and replace, shift everything at once.
- Any format – keep the original, or turn a landscape video into 9:16, 1:1 or 4:5 with a blurred background.
- Songs and podcasts – audio becomes a video with a backdrop, your cover image and moving sound bars.
- Two languages at once – show a translation under the original captions.
Why captions matter
Most people scroll social media with the sound off. Captions keep them watching, make videos accessible to deaf and hard-of-hearing viewers and help search engines understand what is said. Burned-in captions show everywhere – in WhatsApp, on TikTok, Reels and Shorts – while an SRT file lets YouTube show subtitles that viewers can switch on and off.
Free, and without uploading
Most online subtitle editors upload your video to their servers, add a watermark and cap free use at a few minutes. Subtitle Studio runs the open Whisper model from OpenAI and the video encoder in your own browser. Your footage never leaves your device, so it also suits unreleased work, client videos and private recordings.
Recognition and translation languages
Whisper recognises about 99 spoken languages. Translations use the translator built into Chrome on computers (about 40 languages) or downloadable Opus-MT models elsewhere (English, German, French, Spanish, Italian, Portuguese, Dutch, Russian, Ukrainian, Arabic, Chinese, Japanese, Hindi and more). Each translation keeps the timing of the original and can be corrected line by line.
Tips for great captions
- Use Short captions for vertical social videos and Long for interviews and films.
- Turn on the safe zones before export, so app buttons do not cover the text.
- Choose Accurate recognition for music, dialects and noisy rooms.
- Read names and numbers once before you publish.

Frequently asked questions
Which languages can I translate into?
In Chrome on a computer about 40 languages, using the translator built into the browser. In other browsers and on phones, downloadable translation models cover English, German, French, Spanish, Italian, Portuguese, Dutch, Russian, Ukrainian, Arabic, Chinese, Japanese, Hindi and more.
Can I translate an SRT file without a video?
Choose the SRT first, then any video or audio it belongs to – the translation needs the timing only, and the video stays on your device. You can also translate the original and export only the new SRT.
How good are the translations?
Good enough to publish after a quick read. Sentences are translated as a whole before they are split back over the captions, which keeps grammar intact. Names and slang deserve a check.
Is Subtitle Studio really free?
Yes. No account, no subscription, no watermark and no limit on minutes or videos. The site is funded by fair advertising, not by your videos.
Is my video uploaded?
No. The video is read, transcribed, translated and encoded in your browser. Only the AI models are downloaded once from Hugging Face (and the translator from Chrome itself); your video is never sent anywhere.
Which formats work?
Videos your browser can play – MP4, MOV, WEBM, MKV – and audio such as MP3, M4A, WAV, OGG and FLAC. You can import SRT, VTT, LRC and ASS subtitles. The result is an MP4 (H.264) that plays everywhere, or SRT, VTT, ASS, LRC and text files.
How long does it take?
On a computer with a current graphics chip a one-minute video is transcribed in about 10–20 seconds and exported in a few seconds. Phones take longer; you see the progress and a time estimate.
Can I use it on my phone?
Yes. Pick a video from your gallery, edit the captions with your finger and share the finished MP4 straight to TikTok, Instagram or WhatsApp. For long videos a computer is faster.
Can I move the captions?
Yes. Drag them up or down on the preview, or set the position, width and number of lines under Style. The safe-zone overlay shows where TikTok and Reels place their buttons.
