Add subtitles to video

How it works

1. 1

   Add video and subtitles

   Drop your video, then upload an .srt file or paste the subtitles. Both stay on your device.

2. 2

   Style and preview

   Pick size, color, outline or background box, top or bottom, and watch the cues appear live on the preview.

3. 3

   Download

   An MP4 with the subtitles burned into the picture, visible in every player.

Why nothing uploads

Other tools send your video to their servers, which costs them money per file, so they add watermarks, cap file sizes, and make you sign up. This tool does the work right here in your browser using your own device. Your file is never uploaded, so there is no wait, no watermark, no size limit, and no account.

Questions

What does "burning" subtitles mean?

The text is rendered permanently into the picture (hardcoded), so it shows everywhere, social feeds, TVs, old players, with exactly the styling you chose. It can't be turned off afterwards.

Where do I get an SRT file?

Most transcription tools (YouTube Studio, Whisper, professional captioners) export .srt. It's a plain text format, you can even write or fix one right in the paste box here.

Can I style the subtitles?

Yes: three sizes, four colors, black outline or a translucent background box, and top or bottom placement. The live preview shows the result as the video plays.

Why don't my cues show in the preview?

Check the timestamp lines, SRT needs the form 00:00:01,000 --> 00:00:03,000. The tool tells you how many cues it recognized.

Do my files get uploaded?

No. The rendering happens in your browser; video and subtitles never leave your device.
