# Captions for Instagram Reels

> Transcribe your Reel with AI in the browser, style the captions, and download a portrait MP4 with them burned in. Nothing is uploaded.

Auto-generate accurate SRT, VTT, or plain-text subtitles from any video or audio using OpenAI's Whisper speech-recognition model running in the browser (WebGPU or WebAssembly), across roughly 100 languages — or upload your own SRT/VTT. From there you can download the file, burn styled TikTok-style captions permanently into the video, or add a soft subtitle track viewers can toggle on and off. Nothing is uploaded; handles up to 1 GB / 2 hours of audio.

## Reels captions without an editor

Captions lift watch time on Reels because so much of the audience keeps the sound off. This tool transcribes your clip locally with Whisper, lets you style the captions with a live preview, and burns them into the picture so they display identically wherever the Reel is shared.

Everything runs in your browser — no upload, no watermark. Need a plain SRT or a toggleable track instead? Both are one click away from the same result screen.

## Frequently asked questions

### Aren't there captions built into Instagram?

Instagram offers auto-captions, but you can't fully control their style or wording and they aren't guaranteed across every placement. Burning your own captions in gives you a consistent look and guarantees they show for every viewer, on Reels, Stories, and the feed.

### Will the captions fit a vertical Reel?

Yes. The tool adapts caption line length to the 9:16 aspect ratio and lets you place text at the bottom or center, so nothing gets cut off by the interface overlays.

### Can I use subtitles I already have?

Yes. Upload an existing SRT or VTT file to skip transcription — then download it in another format, burn the captions into the video, or add them as a soft track.

### Do you upload my video?

No. The Whisper AI transcription runs locally in your browser via WebGPU or WebAssembly, and if you burn captions in, that re-encode runs on your device too. Your file never leaves your computer — once the page has loaded it even works offline.

### What languages are supported?

Whisper was trained on about 100 languages, including English, Spanish, Catalan, French, German, Chinese, Japanese, Arabic, and Hindi. Pick the spoken language from the grid before transcribing (English is the default) so it transcribes accurately.

### Is it really free?

Yes. The caption maker is completely free, with no signup, watermarks, or limits. We make money from our video translation service, not from this tool.
