Captions that stop the scroll

On TikTok, viewers decide in the first second whether they keep watching – and many watch without sound. Big, animated captions that highlight each word as it’s spoken grab attention and make your message impossible to miss.

HeyCaptions gives you the styles top creators use: bold white text with a yellow highlight, karaoke-style word highlighting, pop-in animations and more. Every style is optimized for vertical 9:16 video and keeps the captions clear of the TikTok buttons.

Made for your phone

You don’t need an app or a laptop. Open HeyCaptions in your mobile browser, upload a video from your camera roll and save the captioned video straight back to your phone.

Frequently asked questions

How do I get animated captions on TikTok?

Upload your video here, choose a style like Bold, Viral or Karaoke and download the MP4. Then post it to TikTok as usual – the animated captions are part of the video.

Will there be a watermark?

No. HeyCaptions never adds a watermark or logo to your video.

Where are the captions placed?

Slightly below the center of the frame by default, so they stay clear of TikTok’s buttons and description. Use the Position slider to move them.

Is HeyCaptions really free?

Yes, 100% free. No sign-up, no watermark and no paid “export” step.

What happens to my video?

Your file is only used to create your captions. It is processed on our own servers and permanently deleted as soon as you are done – at the latest 30 minutes after your last activity. We never use your files for anything else.

Which languages are supported?

HeyCaptions recognizes 99 spoken languages, including English, Spanish, German, French, Portuguese, Italian, Dutch, Polish, Turkish, Japanese, Korean, Chinese, Hindi and Arabic. The language is detected automatically.

Are there any limits?

Files can be up to 500 MB and 30 minutes long. MP4, MOV, WEBM, MKV, AVI, MP3, WAV, M4A and most other formats work.

Does it work on my phone?

Yes. HeyCaptions works in any modern browser on iPhone, Android, tablets and computers – no app needed.
