The result is a TikTok-ready video with professional captions — without opening a video editor.

Short-form creators

85% of TikTok videos are watched on mute. Burned-in captions are the single highest-impact change you can make to a TikTok — they keep viewers in the video even when their phone is silent. Capto generates accurate, word-level captions and bakes them directly into a 9:16 MP4 you can upload immediately. No CapCut, no Premiere Pro, no separate export step.

translate

Creators going multilingual

TikTok's algorithm serves content globally. A single video with Spanish or Portuguese captions can reach millions of new viewers who would have scrolled past an English-only clip. Capto translates your transcript into 60+ languages and exports a separate captioned MP4 for each audience — all from one upload.

Educators and coaches

Educational TikToks — study tips, tutorials, cooking methods, fitness coaching — perform significantly better with captions. Viewers can follow along silently, pause and reread, and share with friends without needing audio. Capto's word-level timestamps make the karaoke style that stops the scroll in educational content.

Frequently asked questions

Does TikTok auto-generate captions?add

Yes — TikTok has a built-in auto-caption feature, but it only works in the TikTok app, can't be styled, and is often inaccurate on accents or fast speech. Capto gives you editable, styleable burned-in captions that work across every platform and look exactly how you want them.

What caption style works best on TikTok?add

Bold, high-contrast fonts with a dark outline or solid background work best for scroll-stopping captions. Impact, Bebas Neue, and Montserrat are the top performers. White text with a black outline or a semi-transparent stripe background are both effective. Capto offers all of these plus custom font upload.

Can I add captions to TikTok videos in Spanish or Portuguese?add

Yes — Capto translates into 60+ languages including Spanish, Portuguese, French, Hindi, and Arabic. After transcription, click Translate, pick your target language, and export a separate captioned MP4. You can reach Spanish-speaking TikTok audiences without re-recording.

Does adding captions improve TikTok reach?add

Studies consistently show captioned videos get 40%+ more views and 12% longer watch time on average. 85% of social video is watched on mute — captions are what keep viewers watching past the first few seconds.

How long does it take to add captions to a TikTok video?add

Under 2 minutes for most TikTok-length clips (15 seconds to 3 minutes). Transcription takes about 30 seconds; the burned-in MP4 export takes another 60–90 seconds.

Can I use Capto for free?add

Yes — every account gets 5 free minutes, no credit card required. That's enough to add captions to 2–3 TikTok-length clips before you decide whether to buy credits.
