Frequently asked questions
Why should I add captions to my TikTok videos?
Studies show that 80% of TikTok users watch with sound off. Captions keep viewers engaged, boost watch time, and can increase engagement by up to 40%. They also make your content accessible to deaf and hard-of-hearing audiences.
What caption style works best for TikTok?
Bold, centered captions with high contrast colors perform best on TikTok. Use a large font size (the viewer is on a phone), keep captions short (1-2 lines), and consider word-by-word highlight animations to match trending TikTok styles.
Does this tool support vertical 9:16 video for TikTok?
Yes. Our caption tool works with any aspect ratio including vertical 9:16 video. Just upload your TikTok-ready clip and the captions will be positioned correctly for the vertical format.
Can I customize the caption font and color?
Absolutely. You can adjust font family, size, color, background, position, and animation style. Match your brand or pick from pre-made styles optimized for TikTok engagement.
