# How to Add Subtitles to a Video (Free, Online)

Add subtitles to any video without a desktop editor. Auto-generate timed captions, edit and style them, then download SRT and VTT or burn them in.

Add subtitles to any video without a desktop editor. Auto-generate timed captions, fix the wording, style them, then download SRT and VTT or burn them straight into the video.

Generate, edit, style, and export subtitles for any video

Adding subtitles to a video used to mean either typing every line by hand in a desktop editor or paying a service and waiting a day. Neither is necessary anymore. Upload your video to Blazescribe and the audio is transcribed with word-level timing, then split into caption lines that already fit on screen. From there it is cleanup, not creation: fix a name, tighten a line, nudge a timestamp that drifted. When the words are right, choose how the captions look with six styles plus size, position, and color, and watch the changes live on the video. The last step is your call. Download an SRT for YouTube and editors, a VTT for the web, or a burned-in MP4 for TikTok, Reels, and Shorts where captions have to be visible the moment a muted clip starts playing. No install, no waiting, no watermark.

## How it works

1. **Upload your video** — Drop in any video up to 1 GB, or record straight in your browser. MP4, MOV, WebM, AVI, and MKV all work.
2. **Auto-generate timed captions** — Blazescribe transcribes the audio with word-level timing and splits it into clean caption lines, ready in minutes.
3. **Edit, style, and export** — Fix any wording, pick a style, then download SRT or VTT, or export a burned-in MP4 with the captions on every frame.

## Capabilities

- **Captions in minutes** — No typing line by line. The transcript becomes timed captions automatically, so you start from a finished draft.
- **Edit and re-time** — Rewrite any line, nudge the start and end in small steps, and merge or split segments so each caption reads cleanly.
- **Six styles, your colors** — Style captions with six presets plus size, position, and color, previewed live on the video before you export.
- **Any format you need** — Download SRT for YouTube and editors, VTT for the web, or a burned-in MP4 for TikTok, Reels, and Shorts.

## FAQ

### How do I add subtitles to a video for free?

Upload the video, let Blazescribe generate timed captions, edit anything that needs a fix, then download SRT or VTT, or export a captioned MP4. You can do all of this on the free plan.

### Do I need to install any software?

No. Everything runs in your browser. There is no desktop editor to install and no project file to manage, and the rendering happens on your own machine.

### Can I add subtitles in another language?

Yes. Translate the transcript first, then edit and export captions in any of 100+ languages with the timing left intact.

### Should I download SRT, VTT, or a burned-in video?

Use SRT for YouTube and most editors, VTT for web players, and a burned-in MP4 for social video where captions need to show even on mute. You can do more than one.
